How can I stop the mouse scroll wheel incrementing and decrementing the values of a GridNumericColumn in my Radrgrid when EditMode="Batch" and EditType="Cell"?

This post suggests using ItemDataBound: http://www.telerik.com/forums/gridnumericcolumn-edit-control
However if I step into the debugger the code:
     if (e.Item is GridEditableItem && e.Item.IsInEditMode)
is never True

Hope you can help?

Hi Mark,

You can use the GridNumericColumnEditor to control the cell in edit mode. Please try the following code snippet.

ASPX:
<telerik:RadGrid ID="RadGrid1" runat="server">
    <MasterTableView  EditMode="Batch">
        <BatchEditingSettings EditType="Cell" />
        <Columns>          
            <telerik:GridNumericColumn UniqueName="Freight" HeaderText="Freight" DataField="Freight" ColumnEditorID="FreightColumnEditor">
            </telerik:GridNumericColumn>        
        </Columns>
    </MasterTableView>   
</telerik:RadGrid>
<telerik:GridNumericColumnEditor ID="FreightColumnEditor" runat="server"
 NumericTextBox-IncrementSettings-InterceptMouseWheel="false" >
</telerik:GridNumericColumnEditor>

Thanks,
Princy

Hi Mark,

Another option for you would be obtain a reference to the RadNumericTextBox rendered as an editor for that column and set the InterceptMouseWheel property to false.

ASPX:
<Columns>
                   <telerik:GridNumericColumn UniqueName="Freight" DataField="Freight"></telerik:GridNumericColumn>
               </Columns>

C#:
protected override void OnPreRender(EventArgs e)
    {
        base.OnPreRender(e);
        RadNumericTextBox numericEditor = (RadGrid1.MasterTableView.GetBatchColumnEditor("Freight") as GridNumericColumnEditor).NumericTextBox;
        numericEditor.IncrementSettings.InterceptMouseWheel = false;
    }

I get the message Telerik.Web.UI.GridException: GridTableView.GetBatchColumnEditor method could be used only when EditMode is set to batch.

Any advise?

Hi Jeffrey,

Batch editing mode is one of the edit modes provided by RadGrid and it can be enabled using the EditMode property of the MasterTableView tag:
https://demos.telerik.com/aspnet-ajax/grid/examples/data-editing/batch-editing/defaultcs.aspx

You can check the following resource to see how you can disable arrow key and scroll navigation in the inner controls when using Batch editing:
https://www.telerik.com/support/kb/aspnet-ajax/grid/details/prevent-numeric-value-changing-with-batch-editing-when-using-keyboard-navigation-with-the-arrow-keys

I am also sending a sample RadGrid web site.

Eyup
