The horizontal scrollbar is not visible in iOS when the grid is empty.

Code to reproduce the problem:
<style>
        html, body, body > form {
            height: 100%;
            padding: 0;
            margin: 0;
        }
    </style>
...
        <telerik:RadGrid ID="RadGrid1" runat="server" AllowPaging="True" Width="100%"
            AutoGenerateColumns="true"
            OnNeedDataSource="RadGrid1_NeedDataSource">
            <ClientSettings>
                <Scrolling AllowScroll="true" />
            </ClientSettings>
            <MasterTableView Width="1500px">
            </MasterTableView>
        </telerik:RadGrid>

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

    private object GetData()
    {
        DataTable dt = new DataTable();
        dt.Columns.Add("column1");
        dt.Columns.Add("column2");
        dt.Columns.Add("column3");
        dt.Columns.Add("column4");
        dt.Columns.Add("column5");
        dt.Columns.Add("column6");
        dt.Columns.Add("column7");
        dt.Columns.Add("column8");

        //dt.Rows.Add(1, 2, 3, 4, 5, 6, 7, 8);

        return dt;
    }

Replicated when the ClickToOpen is enabled: 

protected void Page_Load(object sender, EventArgs e) { RadGrid1.HeaderContextMenu.ClickToOpen = true; }

WORKAROUND: Loading the following script under the script manager

<script>
    var original = Telerik.Web.UI.GridColumn.prototype._onContextMenuItemClicking;
    Telerik.Web.UI.GridColumn.prototype._onContextMenuItemClicking = function (sender, args) {
        original.call(this, sender, args);
                
        var item = args.get_item();
        var itemValue = item.get_value();
        if (itemValue == "FilterList" || itemValue == "FilterMenuContainer" ||
            itemValue == "AggregatesContainer" || itemValue == "FilterMenuParent" || itemValue == "ColumnsContainer" ||
            (Telerik.Web.UI.RadMenuItem.isInstanceOfType(item.get_parent()) && item.get_parent().get_value() == "ColumnsContainer")) {
            if (sender.get_clickToOpen()) {
                args.get_item().open();
            }
        }
    }
</script>

.hasChanges() results in records flagged for Delete to not actually get deleted when .saveChanges() executes.

I found the same behaviour on a LiveDemo example that checks .hasChanges(): Grid - Binding to Telerik ClientDataSource

Steps to reproduce:

  • Make any change to the first record, such as modifying the Contact Name.
  • On the second record, Click the "x" under the DELETE column to mark it for delete.
  • Click any column heading to sort.  (This calls a UserAction event handler that calls .hasChanges())
  • Choose to Cancel at the popup prompt.
  • Click "Save changes".
  • Monitor the browser console, you will find that webservice UpdateCustomers is called,  but DeleteCustomers is not.

The column headings read by JAWS are not great. I see that the rendered table headings have an aria-label attributes, but the text of these labels appears to match the DataField attribute of the grid column. Unfortunately, the DataField is often not the same as the human readable text displayed on the column header. This provides an inconsistent and sometimes confusing experience for screen reader users.

For example, if my data field is named something like full_name_with_title, but my column heading is actually "Full Name," the user will hear fullunderlinenameunderlinewithunderlinetitle, but we'd like them to hear "Full Name". All those underlines are confusing.

It would be much better if Telerik used the HeaderText attribute of the column instead of the DataField attribute. This would ensure that the presentational text and not the internal column names were read to the user.

A temporary workaround can be using the following OnGridCreated handler:

function OnGridCreated(sender, args) {
    if (sender.get_enableAriaSupport()) {
        sender.get_masterTableView().get_columns().forEach(function (col) {
            var header = col.get_element();
            var headerText = (header.textContent || header.innerText).replace(/^\s+|\s+$/g, '');
            header.setAttribute("aria-label", headerText);
        })
    }
}

If paging is disabled and the PageSize is set to less than the number of records bound to RadGrid, client item templates are not all rendered correctly.

Example:

If PageSize is 10, and records bound to Grid are 15, then the first 10 records will have templates rendered correctly, while the rest of 5 records will not.

The problem happens when there is a visible insert row on the grid which gets replaced by an empty row in the exported Excel file. The temp solution is to clear the insert row with the code below and the empty row in the generated excel will be removed.

protected void RadGrid1_ItemCommand(object sender, GridCommandEventArgs e)
{
    if(e.CommandName == RadGrid.ExportToExcelCommandName)
    {
        // if there are items in edit mode, clear those
        if(RadGrid1.EditIndexes.Count > 0)
        {
            RadGrid1.EditIndexes.Clear();
            RadGrid1.Rebind();
        }
            
        // if insert item is present, cancel the insert form
        if (RadGrid1.MasterTableView.IsItemInserted)
        {
            RadGrid1.MasterTableView.GetInsertItem().FireCommandEvent("Cancel", "");
        }       
    }
}

We are still experiencing a problem with the RadGrid and JAWS when aria support is enabled. The JAWS form fields dialog (INS+F5) renders all elements of the grid on a single line.

Assuming the following configuration for RadGrid:

  • RenderMode="Mobile"
  • AllowSorting="true"

Testing using a mobile device (e.g. Chrome in Galaxy Nexus)

Test case 1:

If I click on middle of three dots Icon, then RadGrid opens the options menu

Test case 2:

If I click a bit below of the three dots Icon, then RadGrid does a sort on the column automatically

Hello, 

It would be nice to be able to clear the filter for each column as opposed to creating an external button to clear all filters. I was thinking of similar to below.

Requesting the improvement of this functionality to include scrolling.

 

Brief summary of the issue:

MultiCell selection uses a virtual marque tool to select items and does not include items that are out of view.

I have NEVER seen a real world UI with a GridDropDownColumn in a Grid where you didn't want to save the ValueField of the GridDropDownColumn (ex. Product ID), but also wanted to display the TextField (ex. Product Name) as well as sort and filter by the TextField.  This functionality should be part of the grid and the default behavior for GridDropDownColumn.

I have a Telerik RadGrid, and there is a date column on the grid layout. The date format I am using to display date values is "dd/MM/yyyy". Then, I export that grid data to Excel file with GridExcelExportFormat.Biff type. The problem here is when I open the newly exported Excel file, the date format is changed to "MM/dd/yyyy". 

I want to keep displaying my date format "dd/MM/yyyy" in the Excel file after exporting the grid data.

Issue seems to happen with RadGrid with Bootstrap Skin, RenderMode Lightweight when RequireFieldValidator is enabled in combination with Batch Editing.

Unexpected look (Bootstrap skin):

Other skins seems to have it right.

Expected look (Default skin):

When you have both a Detail Item Template and a Detail Table inside a Grid and then when you show a hidden column using the context menu it only shows for the first row and the grid doesn't display properly.  It also throws the javasecript error "Unable to get property '_getVisibleColumnsCount' of undefined or null reference".

To replicate the problem:

  1. Create RadGrid and bind it a datasource
  2. Set ClientSettings - Selecting - AllowRowSelect to true
  3. Set ClientSettings - EnablePostBackOnRowClick to true
  4. Add a GridEditCommandColumn or a ButtonColumn with Edit/Save/Cancel CommandNames
  5. Enable AJAX for the Grid
  6. Run the application in FireFox

Clicking on the Edit button fires the RowClick event of the Grid instead of Edit/Save/Cancel.
