I have a windows form with a panel that contains a checkbox with the tab index set to zero. When the form loads the checkbox has the focus, but the outline of the checkbox text is not there until you tab away from the first checkbox then back.

Any ideas?

I found the fix that works consistently. Put the code in the paint event of the panel control.

I'm not sure what you mean but you must be aware that the TabIndex property of the checkbox corresponds to the panel

not to the form. You can have the TabIndex of the Panel set to zero and the checkbox tabindex set to zero to have it outlined as the form is first shown. What is probably happening is that another control is getting the focus before the panel. Check your panel tabindex.

It still does not work. You too can reproduce the problem. Create a new windows forms application. On the blank form drag and drop 2 checkbox controls. Set the tab index to 0 and 1 respectively. Run the application. The first checkbox control with tab index of zero is not outlined, even though it has the focus. Hit tab, this will outline the second checkbox. Now hit the up arrow, this will outline the first checkbox.

I need the first checkbox to be outlined when the form loads.

Holy ***, You just found a .Net Framework bug! Now, to who you should report this I don't know, but to get it working it is simple, just write this code:

chkBox2.Focus();

chkBox1.Focus();

I tried that in the form load event, to no avail. I am using VB, not C# though. What event are you placing the code?

Actually the code above wont do the trick, Im trying to figure out how to do it, but probably I'll have to send keyboard input

to get it outlined

I have a fix that works. Thanks.

In the form load add:

SendKeys.Send("{TAB}")

SendKeys.Send("+{TAB}")

That is what I was going to post now. Good, butit is really weird that nobody noticed this before.

Actually this is not even working consistently. Please let me know if you find a different solution. Thank you.

Yeah I noticed that. Put that code on the Form.Shown event. It seems to work nicely
