URGENT! Sys.WebForms.PageRequestmanagerServerErrorException 500 !

Hello,

I have three dropdownlists that filter each other, so, in order to avoid full postbacks i used ur RadAjaxManager. I am getting the following error on some machines:

Sys.WebForms.PageRequestManagerServerErrorException. An error ocurred while processing the request on the server. The Status code returned was:500

Sometimes i get the error.. and it makes it very dificult to debug, because i dont get it even once on my machine and some clients get it..

Strange RadGrid Rendering Behavior in Chrome and IE Compatibility

Hello, I am experiencing a bizarre problem in my radgrid's rendering behavior in IE8 Compatibility Mode and Google Chrome browsers, in Firefox 3.5 and IE 8 it works perfectly. For some reason, the radgrid renders itself at the bottom of the containing panel (IE8 Compatibility Mode) or its header expands indefinitely horizontally (Chrome). I am including the following screenshots of the mentioned problems so that you can aid me in solving this more effitiently. Thanx!!

RadWindow "jumps around" using newest Build in FireFox

Hello,

I recently upgraded to Telerik.Web.UI_2008_3_1327_dev_hotfix. As soon as I did this all RadWindows in Firefox "jump around" and "flash" on the screen. I made a test solution using an older Telerik.Web.UI.DLL and the RadWindow worked fine. Simply changing to the newest .DLL made the radwindow practically unusable in FireFox.

In IE it works/looks just fine.

Is this already a known issue? When can we expect a fix?

Thanks,
ethan

Edit form Template programmatic access

Hi

Hi apologies if this is a silly question but i have searched the forums and help and can’t find an example

I’m using a radgrid with a EditFormType="Template" in the template i have a date picker and 2 timepickers. I would like when i change the datepicker on the postback this updates the selected date of the time pickers. I’ve found lots of examples of how to access the controls when ItemDataBound is called but how can i reference other editform controls programmatically once the editform is showing?

The grid is bound to a sql datasource and the updates and inserts are working perfectly bar the time picker bringing in todays date rather than the date set by the separate date picker.

Many thanks in advance

Ross

GridHyperLinkColumn - Retrieve email address in code behind

Hi! Could someone help me with getting the value of an email address in a GridHyperLinkColumn from the code behind please?

Here's the aspx code:

<telerik:GridHyperLinkColumn DataNavigateUrlFields="Email1" UniqueName="Email1"

DataNavigateUrlFormatString="mailto:{0}" DataTextField="Name" HeaderText="Reviewer" SortExpression="Email1"

ShowFilterIcon="false" ShowSortIcon="false" AutoPostBackOnFilter="true" />

Essentially when a user clicks on a submit button for the RadGrid itself, I would like to grab the email address for each selected row in the grid and send an automated email.

Here's the code behind I have for finding the selected rows in the grid, however, I'm not sure how to retrieve the value of the email address from the GridHyperLinkColumn...

If (RadGrid1.SelectedItems.Count > 0) Then

For Each item As GridDataItem In RadGrid1.SelectedItems

'Add code here to retrieve email address

Next

End If

Any help would be greatly appreciated. Thanks!
