onclientclick question for gridview

i have a gridview with checkboxes for each row. I have a button for update on a checked row (I only want to let people update one row at a time). How can I add a confirm update popup or something similar for a checked row with a particular string in a field?

i.e.
checkbox    product     name    status
[]                 p2              bob      active
[]                 p4                          pending

if someone checks the second row I don't need an update confirmation, but if someone checks the first row I'd like a confirmation since the name field is populated....I can't seem to tweak the javascript for the onclientclick to check for the name field populated or not... i get the confirmation alert for all checkboxes by default... any suggestions?

you can try adding the javascript on the RowDataBound event of the GridView to check if the name column is null/empty or not.

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if ( e.Row.RowType == DataControlRowType.DataRow )
        {
            if ( !String.IsNullOrEmpty(e.Row.Cells[2].Text) )
            {
                CheckBox cb = e.Row.FindControls("<name of your checkbox>") as CheckBox;
                cb.Attributes.Add("onchange", "javascript:alert('hey');");
            }
        }
    }
