I'm trying to intercept a triple-click in a textbox control. I've tried this test code with breakpoints but only a single click is trapped. My goal is to override the double-click and triple-click behaviour to highlight text in custom ways. I had double-click working by handling the DoubleClick event and doing my stuff in there, and then also handling SelectionChanging to override the default behaviour there (or my custom highlighting would be still overridden by the default double-click handling, which is to select the entire current line).

private void TxtboxOnMouseClick(object sender, MouseEventArgs mouseEventArgs)
{
    var clicks = mouseEventArgs.Clicks;
    switch (clicks)
    {
        case 1:
            break;
        case 2:
            break;
        case 3:
            break;
    }
}

Hi Tino,

Thank you for writing.

There is no built-in way to capture the triple click event. However, you can easily achieve it with the help of a timer and if count the performed clicks. This approach is discussed in the following MSDN resource: https://social.msdn.microsoft.com/Forums/vstudio/en-US/c31536a3-2939-4835-a5ae-0c7a23eba36b/how-can-i-process-a-tripleclick-event-on-a-textbox?forum=winforms.

I hope this helps. Let me know if you need further assistance.

Regards,
Hristo
