问题
I'm using winforms with a combobox that has a wider drop down width than it's size. when a user selects something from there, it displays just the ending of the text instead of the beginning. how do i default it to show text starting with the start of the string?
ie. combobox has items
- Atlanta Georgia
- Athens Georgia
- Miami Florida
- ....
and the user picks one and all they see in the box afterwards is "a Georgia"
no, i unfortunately don't have the realestate to make the combobox bigger, and the order of the words in the list won't be changed.
Thanks!

The trick is to call the select after the SelectedIndexChanged event happens:
private void comboBox1_SelectedIndexChanged(object sender, EventArgs e) {
this.BeginInvoke(new Action(() => { comboBox1.Select(0, 0); }));
}

Select position zero by force:
comboBox1.Select(0, 0);
...after the selection is complete and locked in, just call Select.
You could also use:
comboBox1.SelectAll();
...if you want it all highlighted.
