Sir/Madam

My requirement is:

i want to show an alert "You will loose changes you made if you continue. Please press Ok to continue and press cancel to stay on the same page".
and two options "ok" and cancel to be shown on the dialog.

how can i achieve this. This works with onbeforeunload event for normal modal windows but doesn't work with radwindow.

Are there any settings for it 

We are using telerik RAD editor in our application to edit and manage the content. The content in our application contains huge amount of data which includes table, charts, graphs etc.

The controls that contains large tabled hangs when they are clicked. This happens only with IE 9 browser and the functionality works absolutely fine in other browsers.

Please suggest how we can fix this issue as large tables are part of our content.

I am trying to add Telerik’s controls (like RadMaskedTextBox, RadNumericTextBox and RadDateInput controls) dynamically into a user control (under the Page_Init event) which is itself a child of another user control.

 

When I run the project, following exception occurred and nothing is shown in the user control.

“Microsoft JScript runtime error: Sys.ArgumentException: Value must not be null for Controls and Behaviors. Parameter name: element”

 

However, these controls are added directly on a .aspx page without any exception and it appeared that the Telerik’s controls get registered in the Page_PreRenderComplete event of an .aspx page and since this event does not exist in a user control therefore they are throwing the above exception.

Hi!

I am in charge of implementing one (or more than one) mobile test automation solution in my company. My requirements:
- test mobile sites on real devices or iOS simulator via xCode (using Safari);
- test iOS native apps on real devices or iOS simulator;
- test Android native apps, again on real devices or simulators.

Can any of Telerik solutions help me implementing it? Do you know any other solutions then I can use in one of this cases? Thanks!

Hello,

I've seen Infragistics is working on iOS controls.  I was curious if you were planning anything like native iOS or Android controls?  Or is Icenium and Kendo (as in an HTML 5 approach) the approach that Telerik is taking to mobile?

Thanks.

Over the New Year's holiday I had to reset my Windows 8 laptop, so I'm starting over, reinstalling Visual Studio, etc. And of course reinstalling various Telerik controls/suites. I'm installing 16 different ones. I started this yesterday. After 24+ hours, it is still stuck at where it was last night, installing the 9th out of 16. What's wrong? Why is it taking so long? Should I stop it?

Hard to tell if I am posting in the right spot, so please direct me where I can get help if this is not the right area. We are getting the following error when trying to create/edit a user from the backend admin pages. The last time we had this issue, we deleted and recreated the custom fields in the default profile which resolved the problem but it did not this time. Next we just removed the custom fields altogether which still did not resolve the issue. Any direction on how to troubleshoot this error would be much appreciative.
