 This example illustrates how to resize the row header column in [WPF DataGrid](https://www.syncfusion.com/wpf-ui-controls/datagrid) (SfDataGrid)?
 
-[WPF DataGrid](https://www.syncfusion.com/wpf-ui-controls/datagrid) (SfDataGrid) does not provide the direct support to resize the row header column. You can resize the row header column by overriding the [GridRowHeaderCell](https://help.syncfusion.com/cr/cref_files/wpf/Syncfusion.SfGrid.WPF~Syncfusion.UI.Xaml.Grid.GridRowHeaderCell.html) and [GridRowHeaderIndentCell](https://help.syncfusion.com/cr/cref_files/wpf/Syncfusion.SfGrid.WPF~Syncfusion.UI.Xaml.Grid.GridRowHeaderIndentCell.html) by triggering the Thumb.DragDelta event.
