    Hello,

    I have a richtextbox that I am to be able to type in, I want to be able to select the text and flip the case of the selected string. So... "hello world" would magically be "HELLO WORLD". Here is what I currently have, it does not work, but it does not spit any errors at me. Any ideas?

    Code:
       private void lowerCaseToolStripMenuItem_Click(object sender, EventArgs e)
       {
          RichTextBox rtb = (RichTextBox)tabs.SelectedTab.Controls[0]; ;
          rtb.SelectedText.ToLower();
       }
           
    Thanks

    You are just changing the selected text but if nothing is selected its made not to work.

    Try something like this
    Code:
    rtb.SelectedText = rtb.SelectedText.ToLower();
    and see if it works.

    Nice! It does work thanks a ton. I can't believe that I didn't think of that myself, it's so simple.
