how to get asp:panel control which is placed inside Scheduler's Advance Form control

[Richard]

Hi,
I have placed a radcombobox and asp:panel id="Panel1" inside Advance Form control (AdvanceForm.ascx)
I Intend to make panel1 visible or Invisible based on the radcombobox selection using OnClientSelectedIndexChanged event of radcombobox.

Using telerik find method in javascript, I can easily get the telerik control but cant get asp.net controls.
For Example
function StartDateSelected_AdvancedInsert(sender, args) {

        var $ = $telerik.$;
        var endDatejQueryObject = $("[id$='AdvancedInsertForm_EndDate']");
        var endDatePicker = $find(endDatejQueryObject.attr("id"));

}
Its all good for RadDatePicker but when i change it to 

[id$='AdvancedInsertForm_AdvanceControlPanel']it doesn't return any panel control.

Hi Richard ,

To  hide / show an asp.net control you could use the code below:

function selectedIndexChanged(sender, args)
{
    var $ = $telerik.$;
    var panel = $("[id$='Panel1']");
    if (args.get_item().get_text() == "hidden")
    {
        panel.css("visibility", "hidden");
    } else
    {
        panel.css("visibility", "visible");
    }
}

<telerik:RadComboBox runat="server" ID="RadComboBox1" OnClientSelectedIndexChanged="selectedIndexChanged">
    <Items>
        <telerik:RadComboBoxItem runat="server" Text="hidden" />
        <telerik:RadComboBoxItem runat="server" Text="visible"/>
    </Items>
</telerik:RadComboBox>
<asp:Panel runat="server" ID="Panel1" style="visibility: hidden;">
    <asp:TextBox runat="server" />
</asp:Panel>

The panel defined on the page hides/shows depending on the RadComboBox's selected text.

The $find method does not work with asp.net controls, because it tries to find the client object for a control which ID is set as an argument, and for the asp.net controls such an object does not exist.

All the best,
