Do not use selected format when GridClientSelectColumn checked

I am trying to use a grid as part of a user control to get user input. I have a GridClientSelectColumn. What I would like to accomplish is to continue to use the standard row/alternating row formatting when the row is selected, so that the only difference that the user sees is the checkbox is either checked or not.

Any suggestions?

Thanks!

ReflectionPermission; what's creating the error?

We have a telerik site that my developers are trying to move onto a production hosting environment. The hosting environment provides a marginally modified medium trust level. When we try to run the application, we get a security exception error as shown below. I've read the comments about RadUpload ProgressHandler requiring reflectionpermission, but the app is not using RadUploads, and all references to RadUpload and RadUploadProgressHandler have been removed from web.config.

Is there anything else that would be trying to use reflectionpermission? I have no idea where to begin looking for the issue.

Thanks in advance,

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

Loading Dockstates from DB

Hi there

I have been experimenting with loading and saving dock states to a DB but have an issue.

When I run the code the docks are not added to the page - rather they are but the source code has a 'style display:none' so I presume this is hiding the docks?? Its all I can think off as I cant see any other issues.

Can somebody have a look below and see what I am doing wrong........

This is the ASPX.................

<%@ Page Language="vb" AutoEventWireup="false" CodeBehind="Test Docks.aspx.vb" Inherits="IFM_Code_Testing.Test_Docks" %>

<%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>

<telerik:RadCodeBlock ID="RadCodeBlock1" runat="server">

var currentLoadingPanel = null;

var currentUpdatedControl = null;

function RequestStart(sender, args) {

currentLoadingPanel = $find("LoadingPanel1");

currentUpdatedControl = "TableLayout";

currentLoadingPanel.show(currentUpdatedControl);

}

function ResponseEnd() {

//hide the loading panel and clean up the global variables

if (currentLoadingPanel != null)

currentLoadingPanel.hide(currentUpdatedControl);

currentUpdatedControl = null;

currentLoadingPanel = null;

}

</script>

</telerik:RadCodeBlock>

</head>

I cant seem to find any issues apart from the style one mentioned previously.

Any help greatly appreciated

[Solved] How do I rotate through a tabbed multipage user control.

I'm investigating how to reproduce a control on the Oakgov.com website that is used to post news and announcements. The control on this website uses flash, but I think that Telerik controls may be able to reproduce this behavior. Does anyone have an example that I can follow? (It's the control that has tabs labeled Featured, Video, Podcast News/Events.)

Thanks in advance.

[Solved] Replace NavigateUrl with javascript function

Hello,

I build a tagcloud based on the content of a certain text. Everything works great. Gratulations on yet another fine RadControl.

I was wondering however if it would be possible to have the click on a tag trigger a clientside javascript function. Through the click I want to call my highlighting script, which obviously would highlight the clicked tag text in my body text.

Is there any way to achieve this functionality (the javascript function call from a tag).

With regards,

Jeroen
