How to retrieve RadNumericTextbox client object using JQuery selector ID ends with

Is there any other way to retrieve the client object of a RadNumericTextbox control without using server tags to get the ID? Otherwise, I always retrieve 'null' as the result of the selector.

E.g.:

$find("div[id$='_numTxt_wrapper']").attr("id"));

I also notice there is a <div> element with an id ending in "_wrapper".

Hi,

I have a asp LinkButton in RadAjaxPanel. The LinkButton initial text is "Register" and after a event happen it will change to "Unregister". After going to another pages and click on Browsers back button, the LinkButton text is "Register" and not "Unregister". This happen in IE but for Chrome and Mozilla it retain "Unregister" because of viewstate.

Please advise.

Thank you

SharePoint Farm Installation

Hi,

I've been slightly confused as to how to use the installation file for a multi WFE Farm.

Installed on say, WFE 1 fine.

Looking at the GAC on WFE1, I also see the DLLs installed for Web.UI,Skins, Design and Ajax.SharePoint

Trying to install on WFE2 and it states the web parts are already installed (because of rpelication this is correct).

When looking on WFE2 the DLL' do not exist in the GAC. How do I install these?

(We do not have GACUTIL etc installed on the production server and am unable to deploy directly from our Development environment.

Thanks

Using a Delete Command with RowClick enabled.

I have a grid that will display items and when you click on a row it's designed to redirect you to another page where you can edit that items data. My problem is that there is also a delete button that is to be in the row as well and when you click the delete button it fires the OnItemCommand event first which redirects before the delete can occur. So I'm looking for some direction here. If anyone can help I would greatly appreciate it.
