+[WPF DataGrid](https://www.syncfusion.com/wpf-controls/datagrid) (SfDataGrid) allows you to set different [ContextMenu](https://learn.microsoft.com/en-us/dotnet/api/system.windows.controls.contextmenu?view=netframework-4.7.2) for each column using the [SfDataGrid.GridContextMenuOpening](https://help.syncfusion.com/cr/wpf/Syncfusion.UI.Xaml.Grid.SfDataGrid.html?_ga=2.138054064.1225195101.1667794112-766490130.1650530957&_gl=1*jbl2r4*_ga*NzY2NDkwMTMwLjE2NTA1MzA5NTc.*_ga_WC4JKKPHH0*MTY2Nzk4NTI1Mi4yOTMuMS4xNjY3OTkwMjkzLjAuMC4w#Syncfusion_UI_Xaml_Grid_SfDataGrid_GridContextMenuOpening) event.
 
-This example illustrates how to show different context menu for each column in [WPF DataGrid](https://www.syncfusion.com/wpf-ui-controls/datagrid) (SfDataGrid).
+Refer to the following code example to define different `ContextMenu` for each column based on the column index in [SfDataGrid.GridContextMenuOpening](https://help.syncfusion.com/cr/wpf/Syncfusion.UI.Xaml.Grid.SfDataGrid.html?_ga=2.238060544.1225195101.1667794112-766490130.1650530957&_gl=1*bvr10z*_ga*NzY2NDkwMTMwLjE2NTA1MzA5NTc.*_ga_WC4JKKPHH0*MTY2Nzk4NTI1Mi4yOTMuMS4xNjY3OTkwMzc2LjAuMC4w#Syncfusion_UI_Xaml_Grid_SfDataGrid_GridContextMenuOpening) event. Here, the first three columns have different `ContextMenu` and the rest of columns have different `ContextMenu`,
