  can't find FormView control in ItemCommand event

  Dec 22, 2012 03:22 PM|LINK

  When I run the below code the employeeIDLabel has a value of NOTHING.  Shouldn't the FindControl method work?  I referenced the following: http://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.formview.itemcommand.aspx

  'aspx.vb

  Protected Sub fvApplicantComments_ItemCommand(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.FormViewCommandEventArgs) Handles fvApplicantComments.ItemCommand

  If e.CommandName = "Edit" Then

       Dim row As FormViewRow = fvApplicantComments.Row

       Dim employeeIDLabel As Label = CType(row.FindControl("employee_idLabel"), Label)

       If employeeIDLabel IsNot Nothing Then

            If employeeIDLabel.Text <> Session("user_employee_id") Then fvApplicantComments.ChangeMode(FormViewMode.ReadOnly)

       End If  

  End If

  End Sub

  'aspx

  <EditItemTemplate>

        <asp:Label ID="employee_idLabel" runat="server" Text='<%# Bind("employee_id") %>' Visible="true" />

        <asp:LinkButton ID="EditButton" runat="server" CausesValidation="False" CommandName="Edit" Text="Edit" />&nbsp;

  </EdittemTemplate>

  <ItemTemplate>

        <asp:Label ID="employee_idLabel" runat="server" Text='<%# Bind("employee_id") %>' Visible="true" />

        <asp:LinkButton ID="EditButton" runat="server" CausesValidation="False" CommandName="Edit" Text="Edit" />&nbsp;

   </ItemTemplate>

  Try going directly to the FormView:

  Dim employeeIDLabel As Label = DirectCast(fvapplicantComments.FindControl("employeeIDLabel"), Label)

  I got it to work by using the ModeChanged event:

  Protected Sub fvApplicantComments_ModeChanging(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.FormViewModeEventArgs) Handles fvApplicantComments.ModeChanging

  Select Case e.NewMode

  Case FormViewMode.Edit

  Dim employeeIDLabel As Label = fvApplicantComments.FindControl("employee_idLabel")

  If Not employeeIDLabel Is Nothing Then

  If employeeIDLabel.Text <> Session("user_employee_id") Then e.Cancel = True     

  End If

  End Select

  End Sub

  Protected Sub fvApplicantComments_ModeChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles fvApplicantComments.ModeChanged
          If fvApplicantComments.DefaultMode = FormViewMode.Edit Then
              Dim employeeIDLabel As Label = CType(fvApplicantComments.FindControl("employee_idLabel"), Label)
              If employeeIDLabel IsNot Nothing Then
                  If employeeIDLabel.Text <> Session("user_employee_id") Then
                      fvApplicantComments.ChangeMode(FormViewMode.ReadOnly)
                  End If
              End If
          End If
      End Sub

  Programming to simplify, dont look for hard way
