I have an asp.net GridView and I would like to have more than 1 "Select"
button that selects the current row.  I want all of the Select links to do a
PostBack to the current page and then do something based on the
CommandArguement.  Is that possible, and if so, what event do I use to check
the command arguement?  Thanks.

Hi David,

maybe you can use TemplateField for this. Here's little example

<asp:GridView DataKeyNames="CategoryID" ID="GridView1"
       runat="server" AutoGenerateColumns="False"
       OnRowCommand="GridView1_RowCommand"
       OnRowDataBound="GridView1_RowDataBound"
       OnRowDeleted="GridView1_RowDeleted"
OnRowDeleting="GridView1_RowDeleting">
  <Columns>
   <asp:BoundField DataField="CategoryID" HeaderText="CategoryID" />
   <asp:BoundField DataField="CategoryName" HeaderText="CategoryName" /
   <asp:TemplateField HeaderText="Select">
     <ItemTemplate>
       <asp:LinkButton ID="LinkButton1"
         CommandArgument='<%# Eval("CategoryID") %>'
         CommandName="Delete" runat="server">
         Delete</asp:LinkButton>
     </ItemTemplate>
   </asp:TemplateField>
  </Columns>
</asp:GridView>

protected void GridView1_RowDataBound(object sender,
                         GridViewRowEventArgs e)
{
  if (e.Row.RowType == DataControlRowType.DataRow)
  {
    LinkButton l = (LinkButton)e.Row.FindControl("LinkButton1");
    l.Attributes.Add("onclick", "javascript:return " +
    "confirm('Are you sure you want to delete this record " +
    DataBinder.Eval(e.Row.DataItem, "CategoryID") + "')");
  }
}

protected void GridView1_RowCommand(object sender,
                         GridViewCommandEventArgs e)
{
  if (e.CommandName == "Delete")
  {
    // get the categoryID of the clicked row
    int categoryID = Convert.ToInt32(e.CommandArgument);
    // Delete the record
    DeleteRecordByID(categoryID);
    // Implement this on your own :)
  }
}

As you can see, you can put as many linkbuttons you need using
TemplateField and get command using
GridViewCommandEventArgs.CommandName

Hope this helps

Yes, that helps. Thank you so much.
