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.

Update contents of a LoadingPanel on long timed post back

Not sure if this is even possible.

I have an update panel that fires off fine when a button is clicked and it shows "Processing request. Please wait...."

All fine and dandy.

Certain actions may take a while and I would like to be able to change the message content (attempting through threading and delegates) with status updates as to the background process.

Is this even remotely possible?

Open and select value of dropdown box with keyboard

I'm using the spreadsheet component for completing a template file. Several columns have dropdown box values to ensure known values.
Until now I was only able to use the mouse for opening a dropdown box + selecting a value.
The users asked me if there is also a keyboard shortcut way of opening the dropdown box and selecting a value for speeding up the data entry.
