DESCRIPTION

The increment settings of RadNumericTextBox are enabled by default for better convenience when 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

SOLUTION

To resolve that, you can use the PreRender event provided by RadGrid:

<telerik:RadGrid ... OnPreRender="RadGrid1_PreRender">

C#:
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 solution would be to use an external custom editor:
<telerik:GridNumericColumnEditor runat="server" ID="NumBoxEditor1">
    <NumericTextBox runat="server">
        <IncrementSettings InterceptArrowKeys="false" InterceptMouseWheel="false" />
    </NumericTextBox>
</telerik:GridNumericColumnEditor>

And then set it in the column definition:
<telerik:GridNumericColumn ... ColumnEditorID="NumBoxEditor1">
