I have two problems:

1. I'm hiding the panel in which my RadGrid resides, and I show it once a certain LinkButton has been clicked. The problem is when I click the LinkButton to display the panel the first time, the NeedDataSource-event is not triggered. When I click the same button a second time (in succession to the first click), the event is triggered and the RadGrid is filled with data. Doing MyGrid.Rebind() works, but it feels like an ugly solution, seeing how it should bind it automatically?

I heard I could do EnableOutsideScripts="true" but I can't find that property anywhere! I must be dead stupid, I've looked for this property all over yet I can't find it. I have to ask - is it deprecated? According to the object browser, RadAjaxManager inherits from RadAjaxControl, which in turn has the property according to the site (but not according to my object browser). Intellisense isn't picking it up, and manually typing it does no good.

2. I'm binding varying datasources to another RadGrid depending on a set of variables I store in ViewState, this resulted in broken paging on the RadGrid. I read something about ViewState conflicts, but I didn't quite understand how the RadGrid ViewState could interfere with the rest of the page's ViewState.

I'm using the latest version of Teleriks RadControls and .NET Framework 3.5. Tips?

Hello Josef,

The visible/invisible conventions for RadGrid are outlined in this section of the online documentation:

http://www.telerik.com/help/aspnet/grid/grdvisibleinvisibleconventions.html

The EnableOutsideScripts is a property which is present under the Classic versions of RadGrid and RadAjax only. Their ASP.NET AJAX counterparts do not need such property since all client scripts should be registered by the asp ScriptManager control. Thus they will be evaluated when necessary on subsequent ajax requests during the page lifecycle.

Concerning you last question:
There should be no problem to assign different data sources for the grid as long as you refresh the control each time (invoking its Rebind() method) and reset the page index by setting CurrentPageIndex = 0.

Kind regards,
