Response.End() in Sandboxed Solution throws NullReferenceException

Question

Hi,

can I use

Context.Response.Write(

"<script type='text/javascript'>window.frameElement.commitPopup();</script>"); Context.Response.Flush();
Context.Response.End();

in a sandboxed solution ?
Because I allways get a NullReferenceException when I call the End() in my Webpart Code Behind?

Answer 2

I have found a way to close my dialog.

Way 1 works, Way 2 not.

What´s the differnce in the sandbox ?

 

Way 1:

Button btnCancel = new Button();
btnCancel.Text = "Cancel";
btnCancel.Attributes.Add("OnClick", "window.frameElement.cancelPopUp(); return false;");
Controls.Add(btnCancel);


Way 2:

Button btnCancel = new Button();
btnCancel.Text = "Cancel";
btnCancel.Click += new EventHandler(Cancel_Click);


private void Cancel_Click(object sender, EventArgs e){
   this.Context.Response.Write("<script type='text/javascript'>window.frameElement.cancelPopUp(); return false;</script>");
   this.Context.Response.Flush();
   this.Context.Response.End();     
}
