foreach (GridViewRow row in GV_program.Rows)

take it one step at a time until you get it working......
Try this:
/* put this value at the "class level" */
public static readonly int GRID_VIEW_COLUMN_ORDINAL_chkBoxSELECT = 3; /* Your number may be different, its the ordinal column number. A static readonly or const value makes your code more readable IMHO */
/*Then in your method */
if (null != this.GV_program)
{
Control cntl = null;
foreach (GridViewRow gvr in this.GV_program.Rows)
{
cntl = gvr.Cells[GRID_VIEW_COLUMN_ORDINAL_chkBoxSELECT].FindControl("cbSelect");
CheckBox cbIsApproved = cntl as CheckBox;
if (null != cbIsApproved)
{
bool myValue = cbIsApproved.Checked;
}
}
}
I just ran this code, and it worked for me.
protected void imgbutSave_Click(object sender, ImageClickEventArgs e)
{
if (null != this.gvMain)
{
Control cntl = null;
string finalMsg = string.Empty;
int counter = 0;
StringBuilder sb = new StringBuilder();
foreach (GridViewRow gvr in this.gvMain.Rows)
{
counter++;
cntl = gvr.Cells[GRID_VIEW_COLUMN_ORDINAL_chkBoxIsApproved].FindControl("chkBoxIsApproved");
CheckBox cbIsApproved = cntl as CheckBox;
if (null != cbIsApproved)
{
sb.Append(string.Format("Row '{0}' (chkBoxIsApproved.Checked) = '{1}'", counter, cbIsApproved.Checked) + System.Environment.NewLine);
}
}
finalMsg = sb.ToString();
}
}
and my aspx code
<asp:TemplateField>
<ItemTemplate>
<asp:CheckBox ID="chkBoxIsApproved" runat="server" Checked='<%#Eval("IsApproved")%>'>
</asp:CheckBox>
</ItemTemplate>
</asp:TemplateField>
My StringBuilder had all of the checkboxes on my page, with the correct .Checked value.
