thanks for the quick reply that seems to be a good approach. I tried implement it but it doesn't invoke the action when i click on the grid. have i forgot something? (I enabled sorting)

Hello! sorry if this has been asked before, couldn't find anything. I've a gridview populated with data from database. I want to allow user to click on a column, send the action to the server which will recognize the column selected. The only actions I can see send the row which was clicked on, and not the column. For exampel this action:

    protected void MainGrid\_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.DataRow)   
            string s = ((DataRowView)e.Row.DataItem).ToString();
    }

Thanks for help!
