    I have a FormView with an InsertItemTemplate and EditItemTemplate templates.

    Each template contains controls with the same ID.

    Its work’s fine since the controls with the same ID are in different templates.

    I added UpdatePanel to one of the templates to wrap some of the controls and it works exactly as expected.

    When I'm adding UpdatePanel to the second template I got a name conflict compilation error.

    The name conflicts is for the controls inside the UpdatePanel

    I am using AJAX 1.0 RC

     

    Any help would be great.

     

    This are the errors that I got from my sample code

     

    • The type 'Default' already contains a definition for 'Label1'
    • The type ‘Default’  already contains a definition for 'Button2'
    • Type 'ASP.default_aspx' already defines a member called '__BuildControlLabel1' with the same parameter types
    • Type 'ASP.default_aspx' already defines a member called '__BuildControlButton2' with the same parameter types

     

    This is the sample code:

      

    <%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default2.aspx.cs" Inherits="Default2" EnableEventValidation="false" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

    <script runat="server">
        protected void Button2_Click(object sender, EventArgs e)
        {
            Label lbl = FormView1.FindControl("Label1") as Label;
            lbl.Text = DateTime.Now.ToString();
        }

    </script>

    <html xmlns="http://www.w3.org/1999/xhtml" >
    <head runat="server">
        <title>Untitled Page</title>
    </head>
    <body>
        <form id="form1" runat="server">
        <div>
            <asp:ScriptManager ID="ScriptManager1" runat="server">
            </asp:ScriptManager>
            <asp:FormView ID="FormView1" runat="server"
            OnPreRender="FormView1_PreRender" DefaultMode="Insert">
                <EditItemTemplate><asp:UpdatePanel ID="UpdatePanel1" runat="server">
                    <ContentTemplate>
                        <asp:Label ID="Label1" runat="server" Text="Label"></asp:Label>
                        <asp:Button ID="Button2" runat="server" OnClick="Button2_Click" Text="Button" />
                    </ContentTemplate>
                </asp:UpdatePanel>
                </EditItemTemplate>
                <InsertItemTemplate>
                    <asp:UpdatePanel ID="UpdatePanel1" runat="server">
                        <ContentTemplate>
                            <asp:Label ID="Label1" runat="server" Text="Label"></asp:Label>
                            <asp:Button ID="Button2" runat="server" OnClick="Button2_Click" Text="Button" />
                        </ContentTemplate>
                    </asp:UpdatePanel>
                </InsertItemTemplate>
            </asp:FormView>
        </div>
        </form>
    </body>
    </html>

    This is known issue for custom controls (currently VS2005 IDE doesn’t fully support AJAX yet, Orcas will fully support it).

    Thank you for the replay.

    The link in your post ( http://bugcheck/bugs/DevDivBugs/36009.asp ) do not open any bug description…

    Do you know any workaround this problem?

    Thanks

    I'd like to give you two suggestions for you.They should work fine.
    1.Try to change your codes as the following - Place a asp:Formview in a asp:UpdatePanel and specify post back through the triggers
     of the asp:UpdatePanel
    <asp:UpdatePanel ID="UpdatePanel1" runat="server">
    <ContentTemplate>
    <asp:FormView ID="FormView1" runat="server" OnPreRender="FormView1_PreRender" DefaultMode="Insert">
    <EditItemTemplate>
    <asp:Label ID="Label1" runat="server" Text="Label"></asp:Label>
    <asp:Button ID="Button2" runat="server" OnClick="Button2_Click" Text="Button" />
    </EditItemTemplate>
    <InsertItemTemplate>
    <asp:Label ID="Label1" runat="server" Text="Label"></asp:Label>
    <asp:Button ID="Button2" runat="server" OnClick="Button2_Click" Text="Button" />
    </InsertItemTemplate>
    </asp:FormView>
    </ContentTemplate>
    <Triggers>
    <asp:PostBackTrigger ControlID="FormView1" />
    </Triggers>
    </asp:UpdatePanel>
    2.Try to change your codes as the following - Change the asp:Label ID and asp:Button ID in the InsertItemTemplate of the asp:FormView
    <asp:FormView ID="FormView1" runat="server" OnPreRender="FormView1_PreRender" DefaultMode="Insert">
    <EditItemTemplate>
    <asp:UpdatePanel ID="UpdatePanel1" runat="server">
    <ContentTemplate>
    <asp:Label ID="Label1" runat="server" Text="Label"></asp:Label>
    <asp:Button ID="Button2" runat="server" OnClick="Button2_Click" Text="Button" />
    </ContentTemplate>
    </asp:UpdatePanel>
    </EditItemTemplate>
    <InsertItemTemplate>
    <asp:UpdatePanel ID="UpdatePanel3" runat="server">
    <ContentTemplate>
    <asp:Label ID="Label10" runat="server" Text="Label"></asp:Label>
    <asp:Button ID="Button20" runat="server" OnClick="Button2_Click" Text="Button" />
    </ContentTemplate>
    </asp:UpdatePanel>
    </InsertItemTemplate>
    </asp:FormView>

     Wish the above can help you.

    Ditto. I'm using RTM and currently encountering this error. It's a major drag at this stage, too; I'm already past my deadline.

    Hello All,
        What I provided about ASP.NET AJAX bugs fixed in AJAX RTM version here may be not exactly correct because I don't do ASP.NET AJAX forums support from January 2007.Please pay attention to ASP.NET AJAX updates through http://Ajax.asp.net website. Thanks for your attention to ASP.NET AJAX progress.
