I have a scenario in which I have a RadGrid with in-place editing enabled. Several of the columns have custom editors referenced by the ColumnEditorID attribute, and all of the column editors in the grid are Telerik controls. I am catching the ItemCommand event in the code-behind to process the grid commands. The AllowMultiRowEdit attribute of the grid is set to false.

If I click Edit on one of the rows, the row goes into Edit mode correctly, and all of the formatting rules for each column editor are respected (e.g. I have a currency column that displays with a dollar sign and two decimal places, an integer column that displays with no decimal places and no commas, and the numeric columns are aligned right). Now, if I click Edit on a different row, the row that was previously in Edit mode exits edit mode and the second row that was clicked goes into Edit mode, again, as expected. However, the column editors in the second row have now lost the formatting rules. The currency column displays with no dollar sign, the integer column displays with decimal places and commas, and the numeric columns are no longer aligned right.

Note that the formatting is only lost on the editors themselves. The cells, when in view mode, retain their appropriate formatting.

Here is my grid:

                                ID="grdChecksIssued" runat="server" GridLines="None"
                                AllowPaging="True" AllowAutomaticUpdates="true"
                                AllowAutomaticDeletes="True" AllowAutomaticInserts="false"
                                AllowSorting="True" AutoGenerateColumns="False" AllowMultiRowEdit="false">
                                <headercontextmenu cssclass="GridContextMenu GridContextMenu_Default"

                                    AllowMultiColumnSorting="false" EditMode="InPlace"

                                    <EnabledStyle HorizontalAlign="Right" />
                            <telerik:GridNumericColumnEditor ID="gceAmount" runat="server">
                                <NumericTextBox ID="NumericTextBox2" runat="server" MinValue="0" MaxValue="999999999999999.99">

                                DataObjectTypeName="clsDDA" SelectMethod="GetPPAccounts"
                                TypeName="WebLinks.PosPayMain" />

And here is my code-behind:

Private Sub grdChecksIssued_ItemCommand(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridCommandEventArgs) Handles grdChecksIssued.ItemCommand
        Select Case e.CommandName
            Case RadGrid.InitInsertCommandName
            Case RadGrid.EditCommandName
                grdChecksIssued.MasterTableView.IsItemInserted = False
            Case RadGrid.PerformInsertCommandName, _
            Case RadGrid.DeleteCommandName
                Dim hshCells As New Hashtable()
                CType(e.Item, GridDataItem).ExtractValues(hshCells)
        End Select
    End Sub
    Private Sub grdChecksIssued_NeedDataSource(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridNeedDataSourceEventArgs) Handles grdChecksIssued.NeedDataSource
        grdChecksIssued.DataSource = GetRows()
    End Sub

Any help would be greatly appreciated.

Hello Josh,

One suggestion is to try setting the same formatting options for the column editors in the code behind like below.

protected void grdChecksIssued_ItemDataBound(object sender, GridItemEventArgs e)
       if (e.Item is GridEditableItem && e.Item.IsInEditMode)
           GridEditableItem item = (GridEditableItem)e.Item;
           (item.EditManager.GetColumnEditor("SerialNo") as GridNumericColumnEditor).NumericTextBox.MaxLength = 10;
           (item.EditManager.GetColumnEditor("SerialNo") as GridNumericColumnEditor).NumericTextBox.MinValue = 0;
           (item.EditManager.GetColumnEditor("SerialNo") as GridNumericColumnEditor).NumericTextBox.Width = Unit.Pixel(45);
           (item.EditManager.GetColumnEditor("SerialNo") as GridNumericColumnEditor).NumericTextBox.NumberFormat.DecimalDigits = 0;
           (item.EditManager.GetColumnEditor("SerialNo") as GridNumericColumnEditor).NumericTextBox.NumberFormat.GroupSeparator = "";
           (item.EditManager.GetColumnEditor("SerialNo") as GridNumericColumnEditor).NumericTextBox.NumberFormat.DecimalSeparator= " ";
           (item.EditManager.GetColumnEditor("SerialNo") as GridNumericColumnEditor).NumericTextBox.EnabledStyle.HorizontalAlign = HorizontalAlign.Right;

This worked perfectly. Is the ItemDataBound event the preferred place to apply formatting rules to a grid in general, rather than at design time?

This sounds like it might actually be a bug in the grid.  It doesn't make a lot of sense to have to repeat all my editor settings in the event that I have in the markup.  In any event, I can also confirm that this does make it work... I just can't say this "fixes it".
