When you working with sharepoint and you encounter with this error:
The security validation for this page is invalid. Click Back in your Web browser, refresh the page, and try your operation again:
Solution is easy:
set “AllowUnsafeUpdates” propery true.
Example:
Guid webID = SPContext.Current.Web.ID;
Guid siteID = SPContext.Current.Site.ID;
SPSecurity.RunWithElevatedPrivileges(delegate()
{
using (SPSite site = new SPSite(siteID))
{
site.AllowUnsafeUpdates = true;
using (SPWeb web = site.OpenWeb(webID))
{ web.AllowUnsafeUpdates = true; //your code here...
}
}
}
