how do i shift focus?

[Guest]

when the user log into my application, there is a dialog pop up with some
paramereters that need to set.

a radio button is default to checked and a textbox is right next to it. i
want the cursor or the ibeam to flash on the textbox so user don't have to
click on the textbox in order to enter input. how do i shift the focus?

i have the windows form load even with

this.rdTest.enabled = true;
this.txtTest.enabled = true;
this.txtTest.focus();

but it doesn't show the ibeam on the textbox. Can someone tell me how to do
this?

thank you.

txtTest.Select()

Hello!

txtTest.Select()

Correct, calling the Select method does the trick. Another option would be
to say:

this.ActiveControl = txtTest;

However, the way I read the original poster's question, he/she might also
want to consider setting the tab order correctly, in which case calling
Select in the Form_Load event is not necessary. The easiest way to set the
tab order with Visual Studio is to choose the View/Tab Order menu command on
the form design view, and then click the controls one by one in correct
order. Focus (the "ibeam") will then go to the first-clicked control
automatically without any code.

Also, a note about Focus vs. Select methods. From the class library
reference documentation:

"Focus is a low-level method intended primarily for custom control authors.
Instead, application programmers should use the Select method or the
ActiveControl property [...]"

This in addition to what Ciaran has already said.
