ValueMember proprety in ListControls

[Beringer]

I have implemented a combobox and have set the DataSource to an ArrayList.

I next set the DisplayMember and ValueMember properties.

When I run the code the combobox will display the proper text set by
DisplayMember but it seems that the
ValueMember doesn't work correct because when I go to use the SelectValue
property it never displays the correct text in the combobox.

Here is an example of my code:

Initialize combobox (myComboBox):
this.DataSource = Providers;
this.DisplayMember = "FullName";
this.ValueMember = "ID";

Where Providers is an arraylist of provider structs that have "FullName" and
"ID" properties. FullName will return a string and ID will return an
integer (via get accessor).

Then in the initialization code of the dialog box the comobox box belongs to
I do:

myComoboBox.SelectedValue = 3 // for example

After setting the SelectedValue property the text in myComboBox is still the
first item in the ArrayList.

Can someone give me an idea why?
Thank you in advance,

Eric
