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;
    }

System.ArgumentOutOfRangeException
Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index

This error seems to happen if there is a GridTemplateColumn that has the Exportable property set to False.

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.

Keyboard navigation does not work in Firefox 65.0.1

While attempting to implement Keyboard Navigation for one of our RadGrid controls, we discovered that this navigation (Arrow Up/Down and Page Up/Down) did not work correctly in Firefox (though it did within IE, Edge, and Chrome). We also tested the Firefox Keyboard Navigation within the Telerik Grid Demo Site, and experienced the same behavior. 

Issue can also be observed with the Grid - Keyboard Support demo using Firefox 65.0.1

Do you know how to resolve this issue, or of any workaround?

Thank you,
Krassimir

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

Alternating Row style of RadGrid is not applied when using Bootstrap skin.

Steps to reproduce:
For all other Skins these approaches work:
        div.RadGrid tr.rgAltRow {
            background-color: aqua;
        }

Or:
 <AlternatingItemStyle BackColor="Aqua" />

The reason probably is because there is >td directive built-in, which needs to be overridden manually in order for the styling to take effect (this works):
        div.RadGrid tr.rgAltRow > td {
            background-color: aqua;
        }


A possible workaround for this issue is available in the following forum post:

RadGrid GridDateTimeColumnEditor is unable to process data of type TimeSpan if PickerType is set to TimePicker.

As a workaround, a GridTemplateColumn can be used with a TimePicker inside EditTemplate

<telerik:GridTemplateColumn>
	<ItemTemplate>
		<%# Eval("Field") %>
	</ItemTemplate>
	<EditItemTemplate>
		<telerik:RadTimePicker ID="RadTimePicker1" runat="server" SelectedTime='<%# Eval("Field") %>'></telerik:RadTimePicker>
	</EditItemTemplate>
</telerik:GridTemplateColumn>

Hi,

Currently JAWS user cannot use the arrow keys to select a filter operator. Please enable arrow keys support to filter context menu for JAWS user. 
Refer Telerik support ticket - 1081707 for more information.

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.

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();
    }
}

Add support for custom paging in the RadGrid Virtualization functionality. The idea is to enable the retrieval of part of the data from the source of data instead of retrieving all of the data every time.

Without this feature the optimization technique is to cache the data source.

Example is available at http://www.telerik.com/support/kb/aspnet-ajax/grid/details/virtualization-and-custom-paging

Currently Linq2Sql expressions are supported. But as Entity Framework is "de facto" the standard for data access in .NET, it would be great, if you also support ESQL expressions.

This is necessary for example when data binding to entities in OnNeedDataSource event and filter expressions from RadGrid should be used for adapting query.

Thanks,
Roger
