DetailsView does not maintain mode selected in RadWindow

[Daniel]

I have a RadWindow with a DetailsView inside, wrapped with an update panel.

From a regular GridView, an Edit row button, will:

 Select the row on the grid
Change the mode to EditMode on the DetailsView
Then bind the datasource to the DetailsView
Then the RadWindow is displayed

Works Great!

But, the button that is registered as an asynchronous control (during page_load), is clicked the server-side click event is triggered.

At this point, the CurrentMode of the DetailsView is checked.

Is was in EditMode before the dialog was shown

But after the button click, the DetailsView is back in the default InsertMode.

Some troubleshooting steps would be helpful

Hi Daniel,

I would suggest starting off by examining this demo that has a very similar scenario: http://demos.telerik.com/aspnet-ajax/window/examples/internalcontent/defaultcs.aspx.

A few things you could check for are:

• Is ViewState disabled for the control? This can cause state loss
• Is there custom code that resets the mode?
• Does this work outside of a RadWindow?
• If you are using AJAX in the ContentTemplate of the control, do you follow the guidelines from this article: http://www.telerik.com/help/aspnet-ajax/radwindow-ajaxifying.html?
• If you can move the details editing to a separate page and load that in the RadWindow this will encapsulate all its functionality and updates in its own frame so it will not be affected by the main page. This demo shows a similar scenario and you may find it helpful: http://demos.telerik.com/aspnet-ajax/controls/examples/integration/gridandwindow/defaultcs.aspx?product=window.
