Problem with using Ajaxloading panel in master page

I'm getting "Sys.WebForms.PageRequestManager is null or not an object" error when I add an ajaxloadingpanel to the MasterPage

I'm making enablepartialrender of the scriptmanager to false in the master page PageInit(to avoid javascript errors while loading the asp.net report viewer in the child pages).

Not sure if I'm doing anything wrong...below is the code for my master page.

[Solved] Radbutton Requires two clicks to open RadWindow

Hi, I have a RadButton that is supposed to open a radwindow when the "OnClientClicked" is fired. However, the first time this gets fired, nothing happens. The second time I click on the button...the radwindow opens up. Am I missing some code? I am basing this on your demo: http://demos.telerik.com/aspnet-ajax/button/examples/slideshow/defaultcs.aspx.

Here is the code that I have:

<telerik:RadCodeBlock ID="rcb1" runat="server">

<script type="text/javascript">

function ShowInsertForm() {

var combo = $find("<%= RadComboBox1.ClientID %>");

var comboItem = combo.get_selectedItem();

if (!comboItem) {

window.radopen("AddComment.aspx", "UserListDialog");

}

else {

var string = comboItem.get_text();

window.radopen("AddComment.aspx?ID=" + comboItem.get_value(), "UserListDialog");

}

return false;

}

</script>

</telerik:RadCodeBlock>

<telerik:RadButton ID="AddComment" runat="server"

AutoPostBack="false" Text="Add Comment" CommandName="Right" OnClientClicked="ShowInsertForm">

</telerik:RadButton>

<telerik:RadButton runat="server" ID="btnUpdate" Skin="WebBlue" Text="Update Recipient"></telerik:RadButton>

</div>

</telerik:RadAjaxPanel>

<telerik:RadWindowManager ID="RadWindowManager1" runat="server" EnableShadow="true" Skin="WebBlue">

<Windows>

<telerik:RadWindow ID="UserListDialog" runat="server" Title="Add Comment" Width="755px" Height="460px"

ReloadOnShow="true" ShowContentDuringLoad="false" Modal="true" />

</Windows>

</telerik:RadWindowManager>

I can use a plain old button, and it fires off without a second click, but I would really like to use the radbutton since that will keep my styling the same.

Thanks!

Multiselection dropdown, Default Text

Hi,

I'm displaying a Combobox with multiple item selection by means of a checkbox. Does not allow custom text. The problem is that the default text displays always the first item. Is there any way to display the default text as blank or a custom text (by not setting the 'Allow Custom Text' property to true?)

Thanks.
