my code was working fine but i changed a few things and now i cant figure it out.
the problem is that when i click my edit button none of the items go into the listbox. i added a label to track th error and i narrowed it done to a smaller ssection. Please help

Have you checked it's Databound? Try adding a Gridview1.DataBind() statement before accessing the Rows.Count property.|||ill give that a try.
I added a e.rowsaffected on the pageload for a count and it returns the correct number in the gridview on the page load. Then when i click my edit button it still says the number of rows but the other label still says 0. Ill try what you said, hopefully that works

ok the label now returns the correct count but i have narrowed down the problem to my function that checks for the check boxes.
protected int SetStringArraySize() { Label4.Text = GridView1.Rows.Count.ToString();int count = 0;for (int i = 0; i < GridView1.Rows.Count; i++) { GridViewRow row = GridView1.Rows[i];bool isChecked = ((CheckBox)row.FindControl("UpdateCheckBox1")).Checked;if (isChecked ==true) { count++; } }return count;//returns number of checkboxes that are checked }
This always returns 0. my guess is it is not finding the control "UpdateCheckBox1" so here is the html code to go with it where i specify the check box and it shows up and is functional.

is actually correct below. I just tried changing the name to see if that was it.
==========================================================
<asp:TemplateField>
<ItemTemplate>
<asp:CheckBox ID="UpdateCheckBox1" runat="server" />
</ItemTemplate>
<HeaderTemplate>
<input id="UpdateCheckBox1" onclick="javascript:SelectAllCheckboxes(this);" runat="server"
type="checkbox" />
</HeaderTemplate>
</asp:TemplateField>
