Block access to controls in the page on ajax postback

[Meenakshi Nagalingam]

Hi,

We are using Telerik control of version 2009.2.701.35.

In our application we have requirement as when the user performs any ajax postback operation till the operation is completed the user should not be able to perform another operation (like clicking another button in the page) and so the screen should be like readonly.

We have a master page which is common for all pages in the application. Currently In the master page on Ajax OnResponseStart event we get the form tag and make it disabled and OnResponseEnd event we get the form tag and make it enabled.

In this scenario UI shows the whole screen as disabled on request start but the user is able to perform any operation.

Please let us know if there is any option to implement this functionality using RadAjax controls.

Thanks

Hi Meenakshi,

Why not use the RadAjaxLoadingPanel control, its purpose is this exactly - to show loading indication and to prevent user interaction with the controls during AJAX requests:

You can see how to show it over the whole screen here:

Kind regards,
