Fetching control values from a gridview TemplateField

by msch.prv@gmail.com on 1/2/2008 10:52:00 PM I have a gridview wich contains a mix of boundfields and
templatefields. While the boundfields can be retrieved w/o problems, I
am at a loss to get the values of the template fields. I googled
around and tried various methods to no avail.

TIA for any pointers.

Protected Sub grdOrders_SelectedIndexChanged(ByVal sender As Object,
ByVal e As System.EventArgs)
  Dim rowIdx As Integer = Me.grdOrders.SelectedRow.RowIndex
  Dim strTmp As String

  strTmp = Me.grdOrders.Rows(rowIdx).Cells(0).Text ' first column
  strTmp = Me.grdOrders.Rows(rowIdx).Cells(1).Text ' Works OK
  strTmp = CType(Me.grdOrders.Rows(rowIdx).FindControl("lblUser"),
Label).Text ' Empty
  strTmp = CType(Me.grdOrders.Rows(rowIdx).Cells(2).Controls(1),
Label).Text ' Empty
  strTmp =
CType(Me.grdOrders.Rows(rowIdx).Cells(2).Controls(1).FindControl("lblUser"),
Label).Text ' Empty
End Sub

<asp:GridView ID="grdOrders" DataKeyNames="OBaseID"
DataSourceID="sdsCustOrders"
   runat="server" AllowSorting="True"
   OnSelectedIndexChanged="grdOrders_SelectedIndexChanged">
   <Columns>
      <asp:CommandField ShowSelectButton="True" />

      <asp:BoundField DataField="UserName" HeaderText="Status" />

      <asp:TemplateField HeaderText="User" >
          <ItemTemplate>
              <asp:Label ID="lblUser" runat="server"><%#Eval("UserName")%></
asp:Label>
          </ItemTemplate>
      </asp:TemplateField>
   </Columns>
</asp:GridView>
 

Re: Fetching control values from a gridview TemplateField

by Eliyahu Goldin on 1/3/2008 7:17:00 PM Your FindControl call is fine. The problem could be that Label.Text doesn't
come back in the postback. Replace the label with a textbox and see if it
works.

few hours trying to figure this out.

Happy New Year!
