Visual Basic Binding a datasource to a comboBox

I've got a silly question with regards to Visual Basic Express 2010

Basically I'm attempting to bind a datasource to a comboBox in a Dialog attached to a MainForm.

If I were to do it to a textBox it works perfectly:

Dim aBinding As Binding
aBinding = New Binding("Text", MainForm.theBindingSource, "Style")
aTextBox.DataBindings.Add(aBinding)
genderComboBox.selectedIndex = 0

This works perfectly. aTextBox gets populated with the first entry in the table "Style" from MainForm.theBindingSource. Also genderComboBox is set correctly.


However when I attempt to do this with a combobox:

aBinding = New Binding("Text", MainForm.theBindingSource, "Style")
aComboBox.DataBindings.Add(aBinding)
genderComboBox.selectedIndex = 0

The comboBox remains unpopulated. The genderComboBox is correctly set.

I assume this is due to the "Text" property not being correct for the ComboBox however if I tried it with "Items" it didn't work either and genderComboBox doesn't get set either. I'm stumped.

I'm sure that there is a very easy answer to this question but I've been banging my head against a wall for a while now. This is for an assignment in case anyone was wondering and whether that changes how much you wish to tell me.

Thanks in advance!
