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:

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.

Hi

Since updating to the latest release of UI for ASP.NET AJAY the RadContextMenu of my RadGrid is misaligned at the right edge of the screen. Even in your sample https://demos.telerik.com/aspnet-ajax/grid/examples/columns-rows/columns/context-menu/defaultcs.aspx when you open the context menu at the right side of the screen the context menu is nor aligned to the left (like it used to be).

Please ses the attached printscreen.

Kind regards

In GridTableView.cs, you provide a function
 protected virtual GridTableView CreateTableView() (Line 7828).
This function can be overloaded to return derived classes from GridTableView.

But, this is not overloadable completely. Because you create a GridTableView directly in protected void BuildDetailTablesFromDataSource() (Line 8808), too.
There you would have to call a virtual creator function, too.

This is necessary, because I have a lot of Trouble with your DataBind which I was able to fix with an overload. It is much to hard to make this bug visible for you, I really tried to do so already, but I had to fix this that way, because your GridTableView without my derivation fails in our szenario.

The call stack for that problem, I'd had to fix, is always like:
Exception of type 'System.Web.HttpUnhandledException' was thrown. ---> System.IndexOutOfRangeException: Cannot find column CheckSum.

In that, your DataTableView gets an invalid sort Expression string. Therefore, I overwrote DataBind.

But this is not possible in all cases, if you create GridViewTable() objects on your own.

Best regards

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();
        }

Would be great if font awesome could be used for the radgrid edit/delete/ icons etc....
