Question

I’m building a email client in c# that allows users to send HTML emails. I have some general formatting capabilities including the option to insert bulleted and numbered lists. I want to allow users to tab through the controls, but also use the tab key to indent the bullets or numbers in their list. Is there a way to escape TabStop within a certain control, a webBrowser control in particular?

Answer 1

David sparked the idea, but I’d like to give a little more detail. I used mshtml to actually insert the indent and outdent. Just that still moved to the next control, so adding e.IsInputKey = true actually kept the cursor in the webBrowser control so the user can continue typing.

  private void webBrowser_PreviewKeyDown(object sender, PreviewKeyDownEventArgs e)
  {
     if (e.KeyData == Keys.Tab)
     {
        webBrowser.Document.ExecCommand("Indent", false, null);
        e.IsInputKey = true;    //prevents going to next control
     }
     else if (e.KeyData == (Keys.Shift | Keys.Tab))
     {
        webBrowser.Document.ExecCommand("Outdent", false, null);
        e.IsInputKey = true;
     }
  }
