If AllowPaging, AllowScroll and UseStaticHeaders are set to true, then there will be 2 empty <th> elements

workaround: 
    <ClientSettings>
...
        <ClientEvents OnGridCreated="OnGridCreated" />
    </ClientSettings>

<script>
    function OnGridCreated(sender, args) {
        var emptyth = $telerik.$(sender.get_element())
            .find("th").filter(function (ind, item) { return item.textContent == "" });
        // alert(emptyth.length)
        emptyth.append("<span style='display:none'>Hidden empty table header</span>")
    }
</script>

Currently when doing a Batch Edit with the Grid each row and cell must be updated with a new/edited value before saving.

Example: a User has a Grid containing records and would like to update several records because a Date field requires updating.

Can it be possible for the User to select the Rows they would like to update, Edit the Date Field(using the example above), but this time when Saved all records that were selected are updated. 

This solution may require a modal to be displayed that shows all fields available, similar to Edit/Insert grid Popup. The appropriate field is then updated and saved only to selected records.

This feature would save a lot of time by not having to edit each row individually then saving.

When Scrolling is enabled with Frozen columns in RadGrid, horizontal scrollbar not visible in Microsoft Edge.

Issue appears in Microsoft Edge Version:
- Microsoft Edge 42.17134.1.0
- Microsoft EdgeHTML 17.17134



WORKAROUND:

Apparently, setting the horizontal scrollbar's height to 17 pixels will make Microsoft Edge display it. (Note: in case it still not displaying, you may try with 18px)

To set the height, you can choose one of the options below:

1. Using CSS style to increase the size of the horizontal scrollbar by one pixel.

<style type="text/css">
    .RadGrid div[id$="_Frozen"] {
        height: 18px;

        /* or  */
        /*padding-bottom: 1px;*/
    }
</style>


2. Using JavaScript

Subscribe the grid to its GridCreated client-side event, and in the event handler increase the element's height with the scrollbar then revert it back to its original size with a delay:

<script type="text/javascript">
    function GridCreated(sender, args) {
        $('div[id$="_Frozen"]').height(17);
    }
</script>

With form decorator the checkboxes jump a bit to the left when cell is opened: https://www.screencast.com/t/5HwXW6kgVhb

Without form decorator they get centered because of the 100% width they get https://www.screencast.com/t/oxc75Bu6lM

It comes from the combination of two things:
- by default, the grid cells have a left padding (as well as padding to the other sides, but that's irrelevant now)
- the batch editing container does not have left padding so the editable element can better align with the text in the general case (textboxes and other editable elements usually have some left padding). With a checkbox there is no textual input, though, and so it appears to shift to the left because the left-padding of the cell is removed by the batch editing.

Workaround:

		<style>
			/* note: the margins may vary in different skins, inspect the rendering if there is a  */

			/* for form decorator */
			html .RadGrid td.rgBatchCurrent .rfdCheckboxUnchecked,
			html .RadGrid td.rgBatchCurrent .rfdCheckboxChecked,
			html .RadGrid td.rgBatchCurrent .RadCheckBoxList {
				margin-left: 12px;
			}

			/* if no form decorator */
			html .RadGrid td.rgBatchCurrent input[type='checkbox'] {
				width: auto;
				margin-left: 16px;
			}


			/* in case you have radio buttons even though they are not a supported editable control with batch editing*/
			/* for form decorator */
			html .RadGrid td.rgBatchCurrent .rfdRadioUnchecked,
			html .RadGrid td.rgBatchCurrent .rfdRadioChecked,
			html .RadGrid td.rgBatchCurrent .RadRadioButtonList{
				margin-left: 12px;
			}

			/* if no form decorator */
			html .RadGrid td.rgBatchCurrent input[type='radio'] {
				width: auto;
				margin-left: 16px;
			}
		</style>

Hidden columns are shown on resize when the static headers and frozen column are used.

Video: https://www.screencast.com/t/4Lwuvbp7


Possible workarounds:

- Hide the column with Visible="False", instead of Display="False"

- Hide the column on the client-side:



    function gridCreated(sender, args) {
        var masterTableView = sender.get_masterTableView();
        columnIndex = masterTableView.getColumnByUniqueName("ShipName").get_element().cellIndex;
        setTimeout(function () {
            masterTableView.hideColumn(columnIndex);
        }, 2);
    }




Steps to reproduse:

            <telerik:RadGrid RenderMode="Lightweight" HeaderStyle-Width="200px"
                AutoGenerateColumns="false"
                ID="RadGrid1"
                OnNeedDataSource="RadGrid1_NeedDataSource"
                Width="100%"
                runat="server">
                <ClientSettings>
                    <Scrolling AllowScroll="True" UseStaticHeaders="true" FrozenColumnsCount="2"></Scrolling>
                </ClientSettings>
                <MasterTableView AutoGenerateColumns="false">
                    <Columns>
                        <telerik:GridBoundColumn DataField="SongID" HeaderText="SongID" FilterControlWidth="50px" HeaderStyle-Width="50px">
                        </telerik:GridBoundColumn>
                        <telerik:GridBoundColumn DataField="SongTitle" HeaderText="Song Title" FilterControlWidth="200px"></telerik:GridBoundColumn>
                        <telerik:GridBoundColumn DataField="CollectionName" HeaderText="Collection Name" FilterControlWidth="200px"></telerik:GridBoundColumn>
                        <telerik:GridBoundColumn FilterControlWidth="50px" DataField="VersionID" HeaderText="VersionID" Display="false"></telerik:GridBoundColumn>
                    </Columns>
                </MasterTableView>
            </telerik:RadGrid>

Code Behind:

    protected void RadGrid1_NeedDataSource(object sender, GridNeedDataSourceEventArgs e)
    {
        (sender as RadGrid).DataSource = GetData();
    }

    private DataTable GetData()
    {
        DataTable dt = new DataTable();
        dt.Columns.Add("SongID");
        dt.Columns.Add("SongTitle");
        dt.Columns.Add("CollectionName");
        dt.Columns.Add("VersionID");

        for (int i = 0; i < 20; i++)
        {
            dt.Rows.Add(i, i + 1, i + 2, i + 3);
        }

        return dt;
    }

When scroll inside RadGrid in Chrome on a mobile device or in the DevTools responsive/mobile mode, the browser throws [Intervention] Unable to preventDefault inside passive event listener due to target being treated as passive. See  https://www.chromestatus.com/features/5093566007214080. I get 1 error message for every pixel the grid scrolls. 

The problem is due to jQuery and is reproducible with 1.12.4 and 3.3.1 versions of it.

As a temporary workaround you can use Template column with a DataField set.

RadGrid filter command is not triggered for strings containing "and" word.

Video: https://www.screencast.com/t/j649UvPQ3z6

Steps to reproduce:
Filter by "SUNBAY AND LEONA A" in the following demo:
https://demos.telerik.com/aspnet-ajax/grid/examples/functionality/filtering/excel-like-filtering/defaultcs.aspx

Such an exposed method, which returns the value from the ExportOutput, would be useful to further enhance the exporting capabilities of the RadGrid control. A very practical example would be to export numerous RadGrid controls into one Excel file.

It becomes hard to see the checked checkboxes because of the selected color it has by default matches the select color of the grid

Solution:

        .RadGrid_BlackMetroTouch .rgSelectedRow .RadCheckBox.RadButton_BlackMetroTouch .rbToggleCheckboxChecked::before,
        .RadGrid_Bootstrap .rgSelectedRow .RadCheckBox.RadButton_Bootstrap .rbToggleCheckboxChecked::before,
        .RadGrid_Metro .rgSelectedRow .RadCheckBox.RadButton_Metro .rbToggleCheckboxChecked::before,
        .RadGrid_MetroTouch .rgSelectedRow .RadCheckBox.RadButton_MetroTouch .rbToggleCheckboxChecked::before {
            color: white;
        }

        .RadGrid_Glow .rgSelectedRow .RadCheckBox.RadButton_Glow .rbToggleCheckboxChecked::before,
        .RadGrid_Office2010Black .rgSelectedRow .RadCheckBox.RadButton_Office2010Black .rbToggleCheckboxChecked::before,
        .RadGrid_Telerik .rgSelectedRow .RadCheckBox.RadButton_Telerik .rbToggleCheckboxChecked::before,
        .RadGrid_WebBlue .rgSelectedRow .RadCheckBox.RadButton_WebBlue .rbToggleCheckboxChecked::before {
            color: black;
        }

Sample to reproduce the behavior and compare the default colors in other states/cases:

        <telerik:RadCheckBox runat="server" ID="rcb1"></telerik:RadCheckBox>
        <br />
        <telerik:RadCheckBox runat="server" ID="rcb2" Checked="true"></telerik:RadCheckBox>
        <telerik:RadSkinManager runat="server" ID="RadSkinManager1" Skin="Bootstrap" ShowChooser="true">
        </telerik:RadSkinManager>
        <telerik:RadFormDecorator ID="RadFormDecorator1" runat="server" DecoratedControls="All" RenderMode="Lightweight" />
        <asp:CheckBox ID="Checkbox1" Text="some checkbox" runat="server" />
        <telerik:RadGrid ID="RadGrid1" runat="server" OnNeedDataSource="RadGrid1_NeedDataSource" RenderMode="Lightweight">
            <MasterTableView>
                <Columns>
                    <telerik:GridClientSelectColumn></telerik:GridClientSelectColumn>
                    <telerik:GridTemplateColumn HeaderText="rad check box column">
                        <ItemTemplate>
                            <telerik:RadCheckBox runat="server" ID="RadCheckBox1"></telerik:RadCheckBox>
                            <br />
                            <telerik:RadCheckBox runat="server" ID="RadCheckBox2" Checked="true"></telerik:RadCheckBox>
                        </ItemTemplate>
                    </telerik:GridTemplateColumn>
                </Columns>
            </MasterTableView>
            <ClientSettings>
                <Selecting AllowRowSelect="true" />
            </ClientSettings>
        </telerik:RadGrid>

And a dummy data source that is not a good data source in general, but it will suffice to get this running so one can observe

    protected void RadGrid1_NeedDataSource(object sender, GridNeedDataSourceEventArgs e)
    {
        (sender as RadGrid).DataSource = "abcdef";
    }

The ability to freeze columns on the left in a RadGrid is a great feature.  However freezing them from both the left AND right would be even better.

I have a scenario where the far left column in a date field (which is frozen and works great).  Then there are about 30 columns that scroll.  The final column is a "totals" column for that week, and it would be great if that was frozen on the right so I don't need to scroll all the way over to see that column...

Selecting a cell from horizontally scrolled RadGrid with allowed Keyboard Navigationcauses the page to be scrolled to the left in IE 11.

video: https://www.screencast.com/t/4NDOq9Qx

Comment: If the Batch editing is enabled the cell is selected, but the batch editing is not started.

Code to reproduce the issue:
<div style="width: 4000px">
        <telerik:RadGrid ID="RadGrid1" runat="server" AutoGenerateColumns="true" AllowSorting="true" Skin="Telerik" RenderMode="Lightweight"
            OnNeedDataSource="RadGrid1_NeedDataSource">
            <ClientSettings AllowKeyboardNavigation="true" Scrolling-AllowScroll="true" Scrolling-SaveScrollPosition="true">
                <Selecting CellSelectionMode="SingleCell" />
            </ClientSettings>
            <GroupingSettings ShowUnGroupButton="true"></GroupingSettings>
            <MasterTableView  CommandItemDisplay="Top" Frame="Border" ShowFooter="true" AllowPaging="True" AllowCustomPaging="true" ShowGroupFooter="true">
            </MasterTableView>
        </telerik:RadGrid>
</div>

Default values are provided for fields with non-string type in insert mode when RadGrid is bound using Model Binding. The reason behind it, is that the Insert item of the RadGrid is being bound similar to the edit Item and values are then provided by the framework.

Please create an option to remove the default values when inserting a new record.

Using Entity Framework Code First and model binding in a RadGrid, in insert row there is a default value for all non-string types that are not nullable.

For example "0" for Int or Decimal, "01/01/0001" for Date, etc...

So we have to make code to clear these values in textboxs or make SQL requests to give a default value to RadComboBoxs linked to a Foreign Key.

This does not happens using a FormView and model binding.
This does not happens using a RadGrid and EntityDataSource .

Please make an option to let all controls blank in insert mode without doing code !

There are two easy solutions:
- set HighlightDeletedRows to false
- use the built-in Save Changes button in the command item

A workaround is attached that allows you to use an external button and highlight deleted rows.
It will cause other changes apart from deletion on a row to be lost, but deleted rows will be sent to the server.

Due to browser restrictions, the print behavior is changed and works identically to the one of IE - a new tab/dialog with the grid is opened whose print command is launched. You can observe the behavior in IE at https://demos.telerik.com/aspnet-ajax/grid/examples/functionality/printing/defaultcs.aspx. 

Workaround: https://www.telerik.com/support/kb/aspnet-ajax/grid/details/clientdatasource-binding-and-batch-editing-page-is-reset-to-1-after-deleting-a-record

A fix in the codebase of the grid will take time, effort and will have to wait in the queue, which is why this is the official solution.

Hello,

I have Radgrid with editable & non editable columns. I edit a row.

If I click an editable cell, it places the cursor within the editable cell. Its correct.

But if I click a readonly cell, it places the cursor in the first editable cell of the line. If the readonly cell is the last cell of the line and if I click the readonly cell, it places the cursor in the first editable cell. If the grid column width is very large, the grid is scrolled to show the first editable cell, and I loose the data which I am visualizing.

If I click in readonly cell, I want to open all the editable cells of the line, but the page should remain in same place. I don't want to place the cursor in any of the editable cells of the line. 

Example grid:
I have a simple Radgrid with batch mode and edit type row.
I have 3 columns id,name and age.
Id and name columns are editable columns. Age column is non editable column.
If I click on age column which is  non editable , the focus moves to id column, which is the first editable column.
If there many columns in my grid and if I click the last  non editable  column, the grid scrolls to first editable column, and I lose the focus of data which I am seeing.
If I click in  non editable column, I want the grid to remain in same place.

This feature can be added as an option by adding property of grid ForceFocusinEdit.
When ForceFocusinEdit= true, if we click in readonly column, focus moves to first editable column.
When ForceFocusinEdit = false, if we click in readonly column, focus is in clicked cell.

Please refer to Ticket ID: 1168296 for more informations.
Thank you

Repro steps:
- go to the RadClientDataSource binding demo: https://demos.telerik.com/aspnet-ajax/grid/examples/data-binding/client-side/client-data-source-binding/defaultcs.aspx
- filter a column so there is no data in the grid
- remove the filter
Actual: the pager is gone
Expected: the pager is there

SOLUTION: see the following KB article: https://www.telerik.com/support/kb/aspnet-ajax/grid/details/clientdatasource-binding-after-filtering-so-no-records-are-present-and-removing-the-filter-there-is-no-pager
You can show the pager when the filter command is executed:

function OnCommand(sender, args) {
    if (args.get_commandName() == "Filter") {
        $telerik.$(sender.get_element()).find(".rgPager").show();
    }
}

A fix in the codebase of the grid will take time, effort and will have to wait in the queue, which is why this is the official solution.
