Access Selected GridViewRow in GridView

Category: ASP.NET 2.0 - General — Bil@l @ 08:10

Hello:

I was working last night around 3:00 AM, and I found out that in my GridView Column's list, I have added a TemplateField of type LinkButton with CommandName=”EditRec”, in such a way, when the Edit link button is clicked, I want to access the selected GridViewRow, then populate a web form on the same page, and without having to show the “Update” and “Cancel” buttons on the GridView.

I did that, but the problem was now how to access the GridViewRow in the RowCommand method?

I used the “SelectedRow” property but I kept having “Object Reference not ....” I didn't know in fact.

I tried to use GridView1.Rows[e.CommandArgument], but the DataKey I set for the GridView was of type String, so cannot use that either.

I finally was able to use the following and it works fine for me:

if (e.CommandName.Equals("EditRec"))
  {
            string MediaIndex = e.CommandArgument.ToString();

            // Get the last name of the selected author from the appropriate
            // cell in the GridView control.
            GridViewRow selectedRow = (GridViewRow)(((Control)e.CommandSource).NamingContainer);

            string _mediaType   = selectedRow.Cells[0].Text;
            string _CheckOut    = selectedRow.Cells[1].Text;
}

              
The way the code works if as follows:

              
e.CommandSource -> LinkButton

              ((Control)e.CommandSource).NamingContainer -> GridViewRow

              
Then, simply use the Cells property inside the GridViewRow to access all cells.

              
Hope that Helps,

              
Regards
