Documentation "Buttons" not working

[Stephan]

private void SizeModeClick(object sender, EventArgs e)
        {
            RadMenuButtonItem item = sender as RadMenuButtonItem;
            pictureBox1.SizeMode = (PictureBoxSizeMode)Convert.ToInt32(item.Tag);
            sbSizeMode.Text = item.Text;
        }

 

 

 

The above code from the step by step tutorial is throwing a NullReference Exception.  I bolded the line that has the error, VS2012 says it should have a "new", but when i do that it will not compile.


System.NullReferenceException was unhandled
  HResult=-2147467261
  Message=Object reference not set to an instance of an object.

Hi Stephan,

Please find the answer to your question in the support ticket which you have opened regarding the same matter - "Step by Step Tutorial not working".

Kind regards,
Stefan
the Telerik team

I'm having the same problem. A public solution would be much appreciated not just for me but anyone else evaluating the trial.

Regards,

after a bit of experimentation I discovered that the sender object is of type RadMenuItem when in the click event. Modifying the SizeModeClick method as follows produces the desired results:

private void SizeModeClick(object sender, EventArgs e)
{
    RadMenuItem item = sender as RadMenuItem;
    pictureBox1.SizeMode = (PictureBoxSizeMode)Convert.ToInt32(item.Tag);
    sbSizeMode.Text = item.Text;
}

Same problem here. Please help any other great code
