[Solved] $find radtextbox null

[Andreas]

Hi,

I can't seem to reference my textbox from my javascript.

on the aspx:

        <asp:ScriptManager ID="ScriptManager1" runat="server"  EnablePartialRendering="True" EnablePageMethods="True">
            <Scripts>
                <asp:ScriptReference Path="scripts.js" />
            </Scripts>
        </asp:ScriptManager>


        <table cellpadding="0" cellspacing="0">
            <tr>
                <td width="80%">
<%--                            <asp:textbox runat="server" TextMode="MultiLine" id="txt" style="WIDTH: 690px; HEIGHT: 260px" rows="16" Columns="79" ></asp:textbox>&nbsp;
--%>                    <telerik:RadTextBox ID="txt" Width="690" Height="260" Rows = "16" Columns = "79" runat="server" TextMode="MultiLine" SelectionOnFocus="CaretToEnd"></telerik:RadTextBox><br />
                   <asp:TextBox id="txtMsg" Width="400" Runat="server"></asp:TextBox>&nbsp;&nbsp; <input id="btn" onclick="button_clicked()" type="button" value="SEND" class="btn"/>
                </td>

script:

            function button_clicked()
            {
                var RadTextBox = $find("<%= txt.ClientID %>");
                if (RadTextBox == null) {
                    var b = bla;
                }
                PageMethods.SendMessage($get("txtMsg").value,$get("hdnRoomID").value,UpdateMessages, errorCallback);
                $get("txtMsg").value="";
                $get("txt").scrollIntoView("true");
            }

RadTextBox is null..

Any idea what I did wrong?

Thanks,

Andreas

hello,

I did follow that.. and it was returning null, that's why I ask here.

I'm wondering what I did wrong? Because I couldn't see anything suspicious.

Does this always work when RadTextBox inside table cell , update panel, etc?

Thanks,

Andreas

Hello Andreas,

I followed your scenario in order to replicate the issue but to no avail. Please find attached a simple runnable project that demonstrates the desired functionality. Give it a try and let me know if I am leaving something out.
