Grid Loading and Filtering Very Slow... Help!

I have a grid setup for managing users of a website. If you come to the page as an admin, the grid loads a couple thousand records and because of this, takes a couple minutes for the grid to load and is even slower when you try to filter on one of the columns. How can I prevent this? I need to do something like load only the current page of users being shown while still maintaining paging and filtering abilities. Is this something that can be done easily? If not, any suggestions on how to code this?

SPRadEditor Styling

Hi Telerik,

I am using a license Telerik RadControls for SharePoint Q1 2012, v. 12.1.216.0.
My questions are below.

1. How do I apply a default styling for table? What I expect is to add a table, and it will be populated with the default class. Is this achiavable?

2. I have the below control and styling, and I want the user experience that we can just click, then the <a class=".."> will be populated for me. Can you advice a better way to achieve this?

<a class="button">Button</a>

3. I have a duplicated entry in "Apply CSS Style", and the "Dropdown List" is not listed. Please advice.
Here is my classes in ToolsFile.xml. And please look at the attached screenshot ApplyCSSStyle.jpg.

<classes>

<class name="Clear Class" value="" />

<class name="Dropdown List" value="dl.list" />

<class name="Ordered List" value="ol.list" />

<class name="Ordered List (Steps)" value="ol.steps" />

<class name="Unordered List" value="ul.list" />

</classes>

This is the CSS

ul.list,
ol.list { margin-left: 1.5em; }
ul.list li,
ol.list li { margin-bottom: 0.5em; }
ul.list { list-style-type: disc; }
ol.list { list-style-type: decimal; }
ol.list ol.list { list-style-type: lower-alpha; }
dl.list dt { background: url(images/bullet.png) 0 7px no-repeat; padding-left: 10px; font-weight: bold; }
dl.list dd { padding-left: 10px; margin-bottom: 1em; }

ol.steps {
list-style-type: none;
}
ol.steps li { padding-left: 55px; margin-bottom: 0.5em; }
ol.steps li:nth-child(1) { background: url(images/olsteps-1.gif) 0 0 no-repeat; }
ol.steps li:nth-child(2) { background: url(images/olsteps-2.gif) 0 0 no-repeat; }
ol.steps li:nth-child(3) { background: url(images/olsteps-3.gif) 0 0 no-repeat; }
ol.steps li:nth-child(4) { background: url(images/olsteps-4.gif) 0 0 no-repeat; }
ol.steps li:nth-child(5) { background: url(images/olsteps-5.gif) 0 0 no-repeat; }
ol.steps li:nth-child(6) { background: url(images/olsteps-6.gif) 0 0 no-repeat; }
ol.steps li:nth-child(7) { background: url(images/olsteps-7.gif) 0 0 no-repeat; }
ol.steps li:nth-child(8) { background: url(images/olsteps-8.gif) 0 0 no-repeat; }
ol.steps li:nth-child(9) { background: url(images/olsteps-9.gif) 0 0 no-repeat; }
ol.steps li:nth-child(10) { background: url(images/olsteps-10.gif) 0 0 no-repeat; }
ol.steps li:nth-child(11) { background: url(images/olsteps-11.gif) 0 0 no-repeat; }
ol.steps li:nth-child(12) { background: url(images/olsteps-12.gif) 0 0 no-repeat; }

#navbar ul.list,
#content-list ul.list { margin: 0; list-style-type: none; }
#navbar ul.list li,
#content-list ul.list li { background: url(images/bullet.png) 0 7px no-repeat; margin: 0; padding-left: 10px; }

All control auto postbacks are suppressed after upgrade to .NET 4.0

Yesterday, I upgraded our C# ASP.NET solution from .NET 2.0 to .NET 4.0. Other things work fine. But all auto postbacks are suppressed after that.

Our telerik controls are kind of out dated. But because of project timeline, we don’t have time to upgrade our telerik controls for now. I just checked, our RadAjax.Net2 runtime version is v2.0.50727. Out Telerik.Web.UI runtime version is also v2.0.50727.

The following is the code. As you can see with my comments, the drop down list inside the RadAjaxPanel does Not do postback after I select a different value in the list. But the drop down list outside of the RadAjaxPanel works fine.
And this problem is not just for drop down list. It’s for other controls such as radio button DateTimePicker etc. But our buttons are working fine. So it looks like it's the autoposts are suppressed.

<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="Position.ascx.cs" Inherits="Oaccac.WebPmi.Controls.Position" %>
<%@ Register TagPrefix="rad" Namespace="Telerik.WebControls" Assembly="RadAjax.Net2" %>
<%@ Register Src="~/Controls/TelerikAjax/LoadingPanelContent.ascx" TagPrefix="uc" TagName="LoadingPanelContent" %>

<rad:RadAjaxPanel ID="ajaxServiceOfferPanel" LoadingPanelID="ajaxServiceOfferLoadingPanel" runat="server" UseEmbeddedScripts="true" EnableOutsideScripts="true">

<asp:DropDownList ID="ddlTest" runat="server" AutoPostBack="true">
<asp:ListItem>One</asp:ListItem>
<asp:ListItem>Two</asp:ListItem>
</asp:DropDownList>
</rad:RadAjaxPanel>

<asp:DropDownList ID="DropDownList1" runat="server" AutoPostBack="true">
<asp:ListItem>Three</asp:ListItem>
<asp:ListItem>Four</asp:ListItem>
</asp:DropDownList>

<rad:AjaxLoadingPanel ID="ajaxServiceOfferLoadingPanel" runat="server" InitialDelayTime="0">
<uc:LoadingPanelContent ID="loadingServiceOfferPanelContent" runat="server" />
</rad:AjaxLoadingPanel>

Keep selected row focused

Hello,

I'm using a RagGrid on a dynamically loaded UserControl. To keep row selected after postback I followed this:
http://www.telerik.com/help/aspnet-ajax/grid-persist-selected-rows-on-sorting.html

The selected state on the server-side is succesfully set only client-side the record is not selected. When I check the select-item on the OnGridCreated event the count of selected-items is zero.

Can someone help me with this.

Regards,
Jos Meerkerk

RadToolTip Issue

Hello,
I have a textbox which is in invisible mode. I am making it visible on code behind.

RadTooltip is not working for that textbox. Is it because of the textbox is invisible initially ?

If so, how can I solve this ?

Exchange Web Services - resources/custom attributes problem

I am using RadScheduler to bind to Exchange server via Exchange Web Services. The idea is to pull out appointments from different mailboxes on Exchange and display them in the scheduler. I've managed to accomplish this by putting all appointments into a generic list and use that list as a DataSource for RadScheduler. This works like a charm. I need to be able to group these appointments by mailbox (e-mail address of the owner of that appointment). First, I tried to display appointment owner as a resource. There were no way I could accomplish this. Then, it came to my mind that I could display appointment owner as a Custom Attribute.
My question is, how can I programmatically insert Custom Attribute value while appointments are binding?
