RadAjaxManager losing drop down list value after Ajax postback

Hi

I am having a problem with our web app on the search page. My setup is we have a Search.aspx where a RadAjaxManager lives.

From there we have SearchPanel.ascx registered on the search page. This control has its own AjaxEventArgs registered to the OnInit using the Seach.aspx RadManager. This event populates drop down lists with values via an onclick event that is registered to the drop down list control. This works perfectly fine on the first request.

The problem I'm having is when i hit the search button we have registered on that page it fires a seperate AjaxEventArgs with a different AjaxEvent command and it loses the values from the drop down list.

I have undertook the work of upgrading our telerik controls from classic to Asp.Net Ajax control collection (Latest Version) and this previously worked but obviously since I can now only have one manager on the page it seems the behaviour has changed when im hooking up multiple AjaxEventArgs to one manager.

Does this behaviour sound like I have setup any part of the AjaxManager incorrectly or can you point me in any direction I can start looking to resolve this issue? If any more information is required please let me know.

Regards,
Jonathan

Getting values from popup via hot keys into RadEditor

Hi

We want to write a tool in two parts --
1) a popup that will have several rows of 2 associated pieces of information
for ex - 'AAA', 'S1'
'BBB', 'S2' etc.
Each row needs to be associated with a hot key.

2) the main page is the RadEditor
Here when we type, we want to be able to pick up 'AAA' via its associated hot key. When we click a button 'Replace', it will replace 'AAA' with 'S1'.

Are there any tools in Telerik available at this point that can be useful for this purpose? We also need a auto-complete textbox.

Thanks

AJAX callback on RadContextMenu

I’m using the RadControls for ASP.NET AJAX (Q3 2011) and Visual Studio 2010. My website is based on the default web app that comes with Visual Studio. Both RadAjaxManager and RadAjaxLoadingPanel are declared in the Master page…and I use server-side code in each of the content pages to add all the AJAX settings to RadAjaxManager. This works out real nice…but I have a question about something I want to do next. Bear with me as I’m new to using AJAX.

My Master page also contains a RadContextMenu…which I dynamically load in each content page (the menu values differ per content page). The menu item click event triggers an AJAX callback to the content page…where a RadGrid is then updated. The loading panel gets triggered while the grid is loading. I also have a RadComboBox declared on this same content page. When an item is selected there (TextChanged event), I’d like to trigger the same logic as if the user had clicked an item in the RadContextMenu. In other words, I’d like to see the RadGrid get updated AND see the loading panel. I can easily raise the menu item clicked event in the content page, and that code gets executed, but the RadGrid itself doesn’t get updated…and I don’t see the loading panel. I think it might have something to do with the fact that I’m triggering this code from the server-side instead of the client-side. Is there a way on the server-side…to trigger a client-side menu item click event that performs the AJAX callback? Any help would be appreciated. Thanks.

Appearance of RadAsyncUpload

Hello,

How do I retain the initial appearance of the RadAsyncUpload after you select the file to upload? I have the max count at 1 and I want the control to appear with the textbox of the filename (if the filename is long then that textbox should not expand) and the Select button should remain.

Basically, I dont want to see the control to change appearance to the little green dot and red X remove after you select the filename to upload.

Thanks...

RadNumericTextbox in grid behave odd in Chrome browser
