Get value of certain Page control in an asp:Repeater

[greeet]

On my asp.net page, I have several DropDownLists.I also have a Repeater.In the ItemDataBound event I want to get the value of these DropDownLists, to change the data in the Repeater. The SelectedValue of these DropDownLists is empty.But after the ItemDataBound, the Page_Load is executed. There I can get the value of these DropDownLists. Is there a solution to get the value when the ItemDataBound is executed.thanks!Filip
