>How do I determine the index of an item in a combobox based on the valuemember property?<

Are you talking about the selected item of a combobox or do you just want to scan through each item until you find the one you're looking for?

There's quite a few .Selected properties (.SelectedIndex, .SelectedItem, .SelectedIndices, etc.) if that's what you're looking for.

If you just want to scan through each item, then do something like this:

for (int i=0; i < MyCombo.Items.Count; i++)
{
    if (MyCombo.Items[i].ToString() == WhatToLookFor)
    {
        // put code here for finding it
        break;
    }
}
