Question

I have windows forms application with multiple forms and controls in them. I want if user has selected some text in any control of any form of my application and click on cut/copy/paste button on toolbar operation get performed accordingly.

i m using C#.net’s sendkeys.send(“^c”) on click of copy button but it doesn’t work…

OR any 1 can tell if is there any way to get selected text (despite of knowing, which form/control of my application).

Thanks in advance…

Answer 1

I use this in the method handling the copy event:

if (this.ActiveControl is TextBox)
{
      Clipboard.SetDataObject(((TextBox)this.ActiveControl).SelectedText, true);
}
if (this.ActiveControl is RichTextBox)
{
      Clipboard.SetDataObject(((RichTextBox)this.ActiveControl).SelectedText, true);
}
if (this.ActiveControl is ComboBox)
{
       Clipboard.SetDataObject(((ComboBox)this.ActiveControl).SelectedText, true);
}

For paste, something like this:

nCursorPosition = ((RichTextBox)this.ActiveControl).SelectionStart;
this.ActiveControl.Text = this.ActiveControl.Text.Insert(nCursorPosition, Clipboard.GetText());
