Hi All,
I have a problem with a page I'm building at the moment. Basically it includes a multiview with a number of views, in which where there is a usercontrol that contains a number of text fields with custom validators.
Without an updatepanel around the multiview, all works fine. However, when I put an updatepanel around the multiview to prevent full page rendering on postback, the valdidators fail. I have included a very simplified example below to explain my point.
My ASPX Page:
1<%@dotnet.itags.org. Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>23<%@dotnet.itags.org. Register src="http://pics.10026.com/?src=WebUserControl.ascx" TagName="WebUserControl" TagPrefix="uc1" %>4<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">5<html xmlns="http://www.w3.org/1999/xhtml">6<head runat="server">7 <title>Untitled Page</title>8</head>9<body>10 <form id="form1" runat="server">11 <asp:ScriptManager ID="ScriptManager1" runat="server" EnablePartialRendering="true" />12 <br />13 <asp:UpdatePanel ID="UpdatePanel1" runat="server" RenderMode="Inline" UpdateMode="Always">14 <ContentTemplate>15 <asp:Button ID="Button1" runat="server" Text="View 1" OnClick="Button1_Click" CausesValidation="false" />16 <asp:Button ID="Button2" runat="server" Text="View 2" OnClick="Button2_Click" CausesValidation="false" />17 <asp:Button ID="Button3" runat="server" Text="View 3" OnClick="Button3_Click" CausesValidation="false" />18 <br />19 <asp:MultiView ID="MultiView1" runat="server" ActiveViewIndex="0">20 <asp:View ID="View1" runat="server">21 <asp:Label ID="Label1" runat="server" Text="View 1"></asp:Label>22 <uc1:WebUserControl ID="WebUserControl1" runat="server" />23 </asp:View>24 <asp:View ID="View2" runat="server">25 <asp:Label ID="Label2" runat="server" Text="View 2"></asp:Label>26 <uc1:WebUserControl ID="WebUserControl2" runat="server" />27 </asp:View>28 <asp:View ID="View3" runat="server">29 <asp:Label ID="Label3" runat="server" Text="View 3"></asp:Label>30 <uc1:WebUserControl ID="WebUserControl3" runat="server" />31 </asp:View>32 </asp:MultiView>33 </ContentTemplate>34 </asp:UpdatePanel>35 </form>36</body>37</html>38
Code Behind:
1public partialclass _Default : System.Web.UI.Page {2protected void Page_Load(object sender, EventArgs e) {3 }4protected void Button1_Click(object sender, EventArgs e) {5this.MultiView1.ActiveViewIndex = 0;6 }7protected void Button2_Click(object sender, EventArgs e) {8this.MultiView1.ActiveViewIndex = 1;9 }10protected void Button3_Click(object sender, EventArgs e) {11this.MultiView1.ActiveViewIndex = 2;12 }13}The User Control:
1<%@dotnet.itags.org. Control Language="C#" AutoEventWireup="true" CodeFile="WebUserControl.ascx.cs"2 Inherits="WebUserControl" %>34<script type="text/javascript">5 function v(sender, args) {6 var v1 = $get("<%=TextBox1.ClientID%>");7 alert(v1);8 }9</script>1011<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>12<asp:Button ID="Button1" runat="server" Text="Button" CausesValidation="true" />13<asp:CustomValidator ID="RequiredFieldValidator1" runat="server" ControlToValidate="TextBox1"14 Font-Bold="True" Font-Size="X-Large" Text="*" ClientValidationFunction="v" ValidateEmptyText="true" />15
Create the project and add the user control and the default.aspx page. Run it. Try the validator in the View1 (selected by default), it works fine, alerting an [object] to denote the field was found ok.
Switch to another view and all you get alerted is [null] showing the control was not found.
Can anyone get this code to work with the updatepanel?
