Adding a control to an UpdatePanel at runtime

On .Net » ASP.NET AJAX

Hi all,

I have a web page (asp.net 2.0, vs2005) in which I add controls dynamically to a Panel control.

Now I changed the container in an UpdatePanel.

Usually I simply add a newly created control with a statement like this:

PanelContainer.Controls.Add(MyNewControl)

With UpdatePanel do I need to do anything else ?

I asked because my control doesn't get updated correctly.

I tried adding a line

ScriptManager1.RegisterAsyncPostBackControl(MyNewControl);

but with no sucess..

Does anyone have any tips/suggestions/advices ?

Thanks in advance

Bye

Nicola

    • Try out this

      Button btnButton =newButton();btnButton.Text="New Button";

      UpdatePanel1.ContentTemplateContainer.Controls.Add(btnButton);

      my page orginally has this

      <asp:UpdatePanelID="UpdatePanel1"runat="server">

      <ContentTemplate>

      <asp:ButtonID="Button1"runat="server"OnClick="Button1_Click"Text="Button"/>

      </ContentTemplate>

      </asp:UpdatePanel>

    • I tried but it doesn't work (thanks anyway for answering!)

      To clarify my problem: in the page_load I write the text inside the dynamically added control.

      Something like this:

      Textbox MyT = new Textbox();

      MyT.Text = "test string";

      PnlContainer.Controls.Add(MyT);

      In the debugger I see the new value, but it doesn't get updated in the web page.

    • As a Final Statemet of update call this

      UpdatePanel1.Update();

    • I tried but it doesn't work neither.

      I eventually find out that the problem could depend on the third-parties server controls that I am using.

      Thanks anyway for answering
