  Tabcontainer: Add tabs by click on button in UpdatePanel

  Feb 24, 2012 09:05 AM|LINK

  Hi,

  I got a button within an UpdatePanel. This Panel is updated every second to set background color on specified events.

  Now I try to create a new tab by clicking this button.
  
  When I put the TabContainer the new tab exists for 1 second or so. Then the TabContainer gets empty again.
  Without an UpdatePanel it adds the tab of course not.

  Is there any possibility to solve this problem?
  Save the current state of TabContainer is not an option, cause the other opened tabs should not be reloaded.

  Part out of the code:

  <ContentTemplate>
              <asp:TabContainer ID="TabContainer1" runat="server" ActiveTabIndex="1">
              </asp:TabContainer>
          </ContentTemplate>
  
  <asp:UpdatePanel ID="UpdatePanel1" runat="server">
  <ContentTemplate>
  <asp:Timer ID="Timer1" runat="server" Interval="1000">
  </asp:Timer>
                  <asp:Button ID="FehlerButton10" runat="server" Text="Setz" BorderColor="Black"
                      BorderStyle="Solid" BorderWidth="1px" Width="40" />
              </ContentTemplate>
          </asp:UpdatePanel>

      Protected Sub OpenTab(ByVal Url As String, ByVal Title As String)
          Dim tab As New AjaxControlToolkit.TabPanel()
          Dim iframe As New HtmlGenericControl("iframe")
          iframe.Attributes.Add("src", Url)
  
          iframe.Attributes.Add("class", "iframetab")
          tab.Controls.Add(iframe)
          tab.HeaderText = Title
          TabContainer1.Tabs.Add(tab)
          TabContainer1.ActiveTabIndex = TabContainer1.Tabs.Count
      End Sub
      Protected Sub Timer1_Tick(ByVal sender As Object, ByVal e As EventArgs) Handles Timer1.Tick
          Dim Ini As New IniFile("C:\BDE.ini")
          Dim CurrentButton As Button
  
  
          ' through all buttons
          For i = 0 To 15
              ' Find button and cast object to button
              ' Only way to set attributes, sorry
              CurrentButton = CType(FindControl("FehlerButton" & i), Button)
  
              ' Remove all classes
              CurrentButton.Attributes.Remove("class")
  
              ' If errormessage in ini-file is bigger then zero
              If Ini.GetInteger("Fehler", i, 0) > 0 Then
                  ' Set button to error-class
                  CurrentButton.Attributes.Add("class", "ToolbarButtonError")
              Else
                  ' Set button to normal class
                  CurrentButton.Attributes.Add("class", "ToolbarButtonOk")
              End If
          Next i
      End Sub
  
      Protected Sub FehlerButton10_Click(ByVal sender As Object, ByVal e As EventArgs) Handles FehlerButton0.Click
          OpenTab("est.aspx", "Google")
      End Sub
