searching an Item(TextBox) which is in WebDialogWindow template
posted

Hi, what I am doing is searching a text box which is on the WebDialogWindow .

 

<html xmlns="http://www.w3.org/1999/xhtml">

<head runat="server">

    <title></title>

    <script type="text/javascript">   

    function show()    {

        var dialogWindow = $find('<%=WebDialogWindow1.ClientID%>');

        dialogWindow.show();      

    }

    function getdata() {

        var x = $find('<%= TextBox1.ClientID %>');

        alert(x.value);

        return false;

    }

 

</script>

</head>

<body>

    <form id="form1" runat="server">

    <div>    

        <asp:Button ID="Button1" runat="server" onclick="Button1_Click" Text="Button" 

         onclientclick="show();" />    

    </div>

    <ig:WebDialogWindow ID="WebDialogWindow1" runat="server" Height="300px" 

        InitialLocation="Centered" Modal="True" Width="400px" WindowState="Hidden" 

        StyleSetName="Office2007Blue" MaintainLocationOnScroll="True" 

        BorderColor="White" BorderWidth="0px">

        <ContentPane>

            <Template>

                <asp:TextBox ID="TextBox1" runat="server" Text="Amol"></asp:TextBox>

                <asp:LinkButton ID="lnk" runat="server" OnClientClick="return getdata()" Text="Click Me"></asp:LinkButton>

            </Template>

        </ContentPane> 

    </ig:WebDialogWindow>

    <asp:ScriptManager ID="ScriptManager1" runat="server">

    </asp:ScriptManager>    

    </form>

</body>

</html>

 

 

The above scripts works well if used  var x = $get('<%= TextBox1.ClientID %>'); in place of  var x = $find('<%= TextBox1.ClientID %>');.

1) why this is happening as the WebDialogWindow is searched with the same method $find.

2) On some pages when I use <%= %> , the asp.net gives up runtime error that  "The Controls collection cannot be modified because the control contains code blocks (i.e. <% ... %>)",  but when I change it <%# %>, it does not even find WebDialogWindow.

Can someone please explain this.
