Question

User control loses keyboard focus when clicking on anything else on the form

Asked by: prosh0t

Hello.  I have a user control with multiple text boxes on it.  Beside that I have a custom picture box control that I  made that allows you to zoom in by clicking on it with the mouse.  The point is to enter the data on the image displayed from there into my user control that has the multiple text boxes.  The problem is, if I click the picture box to zoom in, then the other control loses the focus of whatever text box the cursor was in.  In fact, if I click anything else in the program (even the file menu) the user control loses the focus and the cursor is no longer in the text box that I was working in.   I would like to keep it.  How do I do that?
 
It almost seems my user control needs to be in a separate thread, but I'm not familiar with how I would go about (or if it's even allowed) creating a user control on a form that exists in a different thread.

I would like to avoid having to handle every 'clicked' event for all the other controls and menus on my form, and handling teh 'lostfocus' event for all the text box's in my control (since that control is actually being switched out constantly with many others like it).  Ie - I'm looking for a very simple way to do this with a minimal amount of code.  Is this possible?

Thanks

It is by design right. When you cllick the mouse outside it, the focus ought to get shifted. What exactly you are trying to address at?

Basically I'd like it to consider the mouse and keyboard focus separate.  If i click somewhere on the GUI with the mouse, the user control should still keep the keyboard focus on the textbox that it was on (ie  you'd still be able to see the cursor blinking in that textbox), so when I start typing again the text will still show up in the text box that the cursor is on, even though you clicked somewhere else.  I don't even know if this is possible without totally revamping the code... I'm starting to think that if it was easy someone would have posted the answer by now.

1)  Try to set the focus of the textbox as mentioned below in all possible events, like mousemove, mousedown, in all possible controls etc

if( textbox1.Focused == false )
 textbox1.Focus();

2) In the update method of the form call this function

private void Form1_Paint(object sender, PaintEventArgs e)
{
  if( textbox1.Focused == false )
    textbox1.Focus();
}
