I use UpdatePanel in my aspx page and DropDownList with onselectedindexchanged method.

When run first time onselectedindexchanged method is working. But change selected again it return an error like that;

Uncaught Sys.WebForms.PageRequestManagerServerErrorException: Sys.WebForms.PageRequestManagerServerErrorException: The state information is invalid for this page and might be corrupted. 

 <asp:ScriptManager ID="ScriptManager1" runat="server" EnableViewState="False" EnableScriptGlobalization="true" >
</asp:ScriptManager>

<%@ Page Title="" Language="C#" AutoEventWireup="true" 
EnableEventValidation="false" ...  %>

Not : I have to Partial Rendering so i cant add EnablePartialRendering="false" to ScriptManager.

How can i solve this problem?

根据上面@Aristos 的评论，通过我的Telerik解决方案，我不得不暂时删除telerik:RadAjaxManager以查看潜在错误。这类似于暂时删除UpdatePanel.

就我而言，错误是：TypeLoadException: Could not load type 'System.Data.Entity.DynamicProxies.RepricingApproval_40D472CCAE59DB7A70B40FC6B029B430955A5ED87A7670652AA5B4D9D96A9A38' from assembly 'EntityFrameworkDynamicProxies-Data, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'.]

（顺便说一句，上面的修复是设置EnableFlattening为假）。
