c# - Perform logout in Sharepoint 2010 Login Control -
i trying customize login control
public partial class logincontrol : usercontrol
in sharepoint 2010 application getting error message after login control performs loggedin event:
system.argumentexception: eine ausnahme vom typ "system.argumentexception" wurde ausgelöst. parametername: encodedvalue bei microsoft.sharepoint.administration.claims.spclaimencodingmanager.decodeclaimfromformssuffix(string encodedvalue) bei microsoft.sharepoint.administration.claims.spclaimprovidermanager.getprovideruserkey(string encodedidentityclaimsuffix) bei microsoft.sharepoint.applicationruntime.spheadermanager.addisapiheaders(httpcontext context, string encodedurl, namevaluecollection headers) bei microsoft.sharepoint.applicationruntime.sprequestmodule.prerequestexecuteapphandler(object osender, eventargs ea) bei system.web.httpapplication.synceventexecutionstep.system.web.httpapplication.iexecutionstep.execute() bei system.web.httpapplication.executestep(iexecutionstep step, boolean& completedsynchronously)
i did research , found out problem cause because users session still open , not logged out.(this issue occurs because invalid user context left in iis cache.)
is there way me ensure user signed out before try sign in user?
