  Update panels change even when updatemode=conditional

  Nov 19, 2012 08:14 PM|LINK

  I have two update panels in the same page, both have their updatemode set to conditional. Inside each update panel are various controls. When I click on the controls in one it changes the other, I thought update panels were meant to stop this?

  Specifically, the text in a databound label (bound to a linq data source) in one update panel vanishes when a checkbox (also databound, but to a different datasource) is clicked in the other.

  The problem only affects the databound control,

  Hi,

  In order to stop it, you can set the UpdateMode as Conditional. Please see the demo below:

  <asp:ScriptManager ID="ScriptManager1" runat="server">
          </asp:ScriptManager>
          <asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional">
              <ContentTemplate>
                  <%=DateTime.Now.ToString() %>
                  <asp:Button ID="Button1" runat="server" Text="Button" />
              </ContentTemplate>
          </asp:UpdatePanel>
          <asp:UpdatePanel ID="UpdatePanel2" runat="server" UpdateMode="Conditional">
              <ContentTemplate>
                  <%=DateTime.Now.ToString() %>
                  <asp:Button ID="Button2" runat="server" Text="Button" />
              </ContentTemplate>
          </asp:UpdatePanel>

  Please see whether the text in a databound label is created in the code behind. When it is created in the code behind, it will be destroied when do a postback.
