Hi, If you going for server side delete which will include your postback then you can register the script by adding the below code once your delete code is executed ClientScript.RegisterStartupScript(this.GetType(),"key", "javascript:alert(deleted successfully');", true); https://msdn.microsoft.com/en-us/library/system.web.ui.clientscriptmanager.registerstartupscript%28v=vs.110%29.aspx Hope you will get it and solves your problem. Plz mark it as answered if it really helped you.

Hi umair, Row deleting or row_updating event gets triggered when you click on button at row level. And Rowdatabound event is triggered when all the data is bound to grid one by one. Rowdatabound is used for doing any modification to data or control while each row of data is bound. Both are for different purpose so dont get confused.

you need item templates to place edit or delete buttons and call javascript by code behind on row data bound or by clientside
