Hello. I first posted this on microsoft.public.dotnet.languages.csharp
because I found that linked to on some website. Since then, I've found this
windowsforms group. Sorry if you're reading this twice; it won't happen
again.

I'm creating an application that requires user input into a ComboBox, and
I'd like to have the cursor appear in this emtpy ComboBox when the
application starts. I had a plain TextBox, and the cursor started there
automatically; to implement a history feature, I've moved to a ComboBox, but
now the user needs to click on it before typing.

How do I set focus on this item? I've tried adding a null string and calling
comboBox.Focus() to no avail. I read somewhere the trick is to set the focus
to the editable text box contained within the ComboBox, but I haven't been
able to figure out how to do that.

Thanks,
-ed

Are there other controls on form? If so, what is the TabIndex of the
ComboBox? Typically the first control in the tab order of a dialog should
get focus when the dialog is displayed. In your form's Design view, click
View->Tab Order to see the overall tab order.

There are a lot of other items in the form, and I never would have thought
of the Tab Order (I thought this was just a navigation control). I set the
ComboBox to 0 and now the cursor is right there when it starts up.

Thanks a lot,
