mouse wheel changes cell value

[Daniel]

When editing a cell, moving the mouse wheel changes the value of the cell. How can I stop this behavior?

Hello Daniel,

The increment settings are enabled by default for better convenience with operating with the input control. You can access the control and disable the arrow navigation of the numbox itself using the approach demonstrated in the following section:
http://docs.telerik.com/devtools/aspnet-ajax/controls/grid/rows/accessing-cells-and-rows#accessing-controls-in-batch-edit-mode

In this case it will be something like this:

Copy Code

Copy Code

Copy Code

protected void RadGrid1_PreRender(object sender, EventArgs e)
{
    GridTableView masterTable = ((RadGrid)sender).MasterTableView;
    GridNumericColumnEditor editor = masterTable.GetBatchColumnEditor("Freight") as GridNumericColumnEditor;
    RadNumericTextBox numBox = editor.NumericTextBox;
    numBox.IncrementSettings.InterceptArrowKeys = false;
    numBox.IncrementSettings.InterceptMouseWheel = false;
}

An alternative approach is the following:

Copy Code

Copy Code

Copy Code

<telerik:GridNumericColumn ... ColumnEditorID="NumBoxEditor1">

Editor definition on the same page with the RadGrid:

Copy Code

Copy Code

Copy Code

<telerik:GridNumericColumnEditor runat="server" ID="NumBoxEditor1">
    <NumericTextBox runat="server">
        <IncrementSettings InterceptArrowKeys="false" InterceptMouseWheel="false" />
    </NumericTextBox>
</telerik:GridNumericColumnEditor>

I hope this will prove helpful.
