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.

Have built-in option to do LIKE filtering on grids.

Description:

If RadGrid has UseStaticHeaders enabled, different HTML Tables are rendered and instructing JAWS to read the tables one by one will also read the Header. It would say Header with "n" number of columns and one rows, since the table has only one row and that is containing the Column Names.

Goal:

It would be great, if the grid with Static Header could be made in a way that JAWS will only treat the grid as one Table instead of two separate tables.

Workaround and discussion:

• https://www.telerik.com/forums/screen-reader-not-reading-number-of-rows-in-grid-for-telerik-radgrid 

Using CommandItemTemplate (Grid - Command Item) for Editing DetailTable records and selecting an item after filtering or from another page, one item from the first page is put for editing instead. Open the attached GIF animation (EditSelectedEditWrongItem.gif) to see it in action.

Currently the workaround we offer is to handle the EditSelected command manually for all the DetailTables Except for the Master.

Grid markup:

        <telerik:RadGrid ID="RadGrid1" runat="server" AllowPaging="True" Width="100%" PageSize="3"
            OnItemCommand="RadGrid1_ItemCommand"
            OnDetailTableDataBind="RadGrid1_DetailTableDataBind"
            OnNeedDataSource="RadGrid1_NeedDataSource">
            <MasterTableView Name="MasterTable" AutoGenerateColumns="true" DataKeyNames="OrderID">
                <DetailTables>
                    <telerik:GridTableView Name="ChildTable" DataKeyNames="OrderID" AutoGenerateColumns="true" CommandItemDisplay="Top">
                        <CommandItemTemplate>
                            <asp:LinkButton ID="btnEditSelected" runat="server" CommandName="EditSelected" CssClass="btn btn-default">Edit Selected</asp:LinkButton>
                        </CommandItemTemplate>
                    </telerik:GridTableView>
                </DetailTables>
            </MasterTableView>
            <ClientSettings>
                <Selecting AllowRowSelect="true" />
            </ClientSettings>
        </telerik:RadGrid>

C# - ItemCommand

    protected void RadGrid1_ItemCommand(object sender, GridCommandEventArgs e)
    {
        // Logic applies for all the tables (detail tables) which are not named "MasterTable"
        if(e.Item.OwnerTableView.Name != "MasterTable" && e.CommandName == RadGrid.EditSelectedCommandName)
        {
            e.Canceled = true;

            GridTableView detailTable = e.Item.OwnerTableView;

            if (detailTable.OwnerGrid.SelectedIndexes.Count == 0)
            {
                return;
            }

            foreach (GridDataItem selectedItem in detailTable.OwnerGrid.SelectedItems)
            {
                selectedItem.Edit = true;
            }

            detailTable.Rebind();
        }
    }

VB - ItemCommand

Protected Sub RadGrid1_ItemCommand(ByVal sender As Object, ByVal e As GridCommandEventArgs)
    If e.Item.OwnerTableView.Name <> "MasterTable" AndAlso e.CommandName = RadGrid.EditSelectedCommandName Then
        e.Canceled = True
        Dim detailTable As GridTableView = e.Item.OwnerTableView

        If detailTable.OwnerGrid.SelectedIndexes.Count = 0 Then
            Return
        End If

        For Each selectedItem As GridDataItem In detailTable.OwnerGrid.SelectedItems
            selectedItem.Edit = True
        Next

        detailTable.Rebind()
    End If
End Sub

Currently the Width of the Edit controls inside the inline Edit form of the Grid can be set only in pixels. In order to be able to implement a responsive layout the developer has to be able to set the width of these controls in percentage.

When virtualization is enabled for RadGrid, NeedDataSource is called at every Post back with RebindReason = ExplicitRebind, regardless of the event target.

Steps to reproduce:

Images that reside in the grid will get resized (scaled down with about 3-5 %) which might cause issues, specially if exporting bar-codes, thus the bar-code scanners won't be able to read them.

Current workaround is to use the Telerik Documents Processing Library  and build the table manually where the images are inserted without changing the size.

Here is an example:

        protected void RadGrid1_InfrastructureExporting(object sender, GridInfrastructureExportingEventArgs e)
        {
            Telerik.Web.UI.ExportInfrastructure.Table table = e.ExportStructure.Tables[0];

            Workbook workbook = new Workbook();
            workbook.Worksheets.Add();

            Worksheet worksheet = workbook.ActiveWorksheet;


            foreach (var row in table.Rows)
            {
                if (row.Index > 1)
                {
                    worksheet.Rows[row.Index - 1].SetHeight(new RowHeight(55, true));
                }

                foreach (var cell in row.Cells)
                {
                    if (row.Index == 1 || cell.ColIndex != 2)
                    {
                        worksheet.Cells[cell.Index.Y - 1, cell.Index.X - 1].SetValue(cell.Value.ToString());
                    }
                    else
                    {
                        FloatingImage image = new FloatingImage(worksheet, new CellIndex(cell.Index.Y - 1, cell.Index.X - 1), 0, 0);
                        Stream stream = File.Open(Server.MapPath(cell.Value.ToString()), FileMode.Open);
                        using (stream)
                        {
                            image.ImageSource = new Telerik.Windows.Documents.Media.ImageSource(stream, "jpg");
                        }
                        worksheet.Shapes.Add(image);
                    }
                }
            }

            byte[] data;

            using (MemoryStream ms = new MemoryStream())
            {
                XlsxFormatProvider xlsProvider = new XlsxFormatProvider();
                xlsProvider.Export(workbook, ms);
                data = ms.ToArray();
            }

            Response.ContentType = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet";
            Response.Headers.Remove("Content-Disposition");
            Response.AppendHeader("Content-Disposition", "attachment; filename=" + RadGridLista.ExportSettings.FileName + ".xlsx");
            Response.BinaryWrite(data);
            Response.End();
        }

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>

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>

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...
