Questions on UI for ASP.NET AJAX Forum

Hi Support,

I am using UI for ASP.NET AJAX Q3 2014.
When I place a slider in a table: <table><tr><td><telerik:RadSlider ... /></td></tr></table>
then the styles are not fully rendered.
Sometimes at page load but not when you press the browser's refresh button.
This problem occurs on IE 11 but not in Chrome.
Is telerik not cross browser compatible?
Is telerik generally not made for IE 11?
Do you have generally problems with including components in a table cell?

Thanks for a Feedback.

Preventing the CDN script

I'm using the RadSiteMap in the context of the sitefinity breadcrumb widget...

So I've overrode the widget itself and have tried everything I can think of to stop the script from loading, but nothing seems to work.

Basically I just need to render out flat markup I dont need any client features of the widget...

this.SiteMapBreadcrumb.RenderMode = RenderMode.Lightweight;

this.SiteMapBreadcrumb.EnableEmbeddedScripts = false;

this.SiteMapBreadcrumb.EnableEmbeddedSkins = false;

this.SiteMapBreadcrumb.EnableEmbeddedBaseStylesheet = false;

Is it possible?

Hi everyone,
Please response to Kassaiefarshad@yahoo.com

I have used RadGrid in a Webpart in Sharepoint 2010. I am not using Ajax.

I have got two problem as follow:
Problem 1:

When I enable Paging in RadGrid it doesn't work.It mean that when I click on page "2" to go to page two, it returns empty page.

My webpart's code is as follow:

<telerik:RadGrid ID="RadGridArzyabiDavari" runat="server" AllowPaging="True"

AllowSorting="True" AutoGenerateColumns="False" CellSpacing="0"

GridLines="None">

{

                 List<ReportsDataSources.ArzyabiDavari> arzyabidavari = new List<ReportsDataSources.ArzyabiDavari>();

if (!Page.IsPostBack)

{

Bind_RadGridArzyabiDavari();

RadGridArzyabiDavari.DataSource = arzyabidavari;

RadGridArzyabiDavari.DataBind();

}

Problem 2:

--------------------------------------------------------------------------------

Script control 'PageSizeComboBox' is not a registered script control. Script controls must be registered using RegisterScriptControl() before calling RegisterScriptDescriptors().

RadGrid and RadMap binded to same RadClientDataSource

I am receiving the attached error when I have a RadGrid and RadMap attached to the same RadClientDataSource. The error occurs by a postback on a Rad drop down. If I bind the two to different RadClientDataSource the error goes away. Unfortunately I would like to keep them bound to the same single RadClientDataSource as I have found when I filter the list of customers (with Lat/Long) the RadMap filters aswell, so was a 'feature' I want to keep. Any thoughts on how I supress this message ?

Visual Style Builder to support LightWeight

Hi,

Will Visual Style Builder be able to support automatically the property RenderMode="Lightweight" in the future ?
From what I gathered in the forms, Visual Style Builder only supports RenderMode="Classic".

I've tried RenderMode="Lightweight" after doing "Visual Style Builder" and Telerik's Skin Builder Assembly Builder Tool (http://skinsassemblybuilder.telerik.com/) ,.. and UI rendering indeed breaks.

Thanks,
Henry Wu
