You can assign runtime validation group to the textbox on rowdatabound event of gridview. asp:requiredfieldvalidator id = "RqFieldValidator1" controltovalidate = "txtEmployeeName" validationgroup = "GeneralInfo" errormessage = "Enter employee name." runat = "Server" > asp:requiredfieldvalidator > protected void GridView1_RowDataBound( object sender, GridViewRowEventArgs e) { if (e.Row.RowType == DataControlRowType.DataRow) { TextBox myTextBox = (TextBox)(e.Row.Cells[1].FindControl( "TextBox1" )); // Depending upon the textbox value insert or update or do whatever if (myTextBox.Text == "" ) { myTextBox.ValidationGroup = " GeneralInfo " ; // To add the validation } else { myTextBox.ValidationGroup = "" ; //To remove the validation } } } You can also write this type of dynamic valdiation on the RowCommand even of gridview. Hope this will help you.

@Anupam We cant remove like that. Better choose custom validator & provide conditions in that.
