e.rowindex

Question

I am getting below errors while i passed the  argument of linkbutton of gridview GridviewCommanEventArgs e?what is mean of it...

and it marked the line below to the [e.RowIndex]; ?

whether the Rowindex can be accept or not for linkbutton tags?

 

 

Error 2 No overload for 'GridView1_SelectedIndexChanged' matches delegate 'System.EventHandler' ;

Error 1 'System.EventArgs' does not contain a definition for 'RowIndex' and no extension method 'RowIndex' accepting a first argument of type 'System.EventArgs' could be found (are you missing a using directive or an assembly reference?)
