I have a RadCombo that stores a list of user names. Every time the User selects a new name, an AJAX call is made and a RadGrid is filled with info for that selected User. Everything is done client-side with no full Postback
In the grid, there is a GridButtonColumn button ("Remove") that uses ClientEvents and a RadScriptBlock to make 2 AJAX calls.
The first one is in the code-behind of the page itself, and the second is on the code-behind of a User Control on the page.
The issue is that between the 2 calls, a partial PostBack takes place and in the Page_Load event, the values for SelectedValue and SelectedText are incorrect. They are initially null/empty, instead of the currently selected item in the RadCombo.
This is key because in the Page_Load event, the current user name is used to fill one of the page's properties. This property is then needed by the User Control code-behind to perform further actions.
Is there a setting to make sure the currently selected values are populated correctly during this sequence?
Thanks.

Hi Online .Net Developers,
Could you provide more details about this partial PostBack which occurs between the two AJAX calls? How it is different than the other two?
