ImageComboBoxEdit selected value not settable - winforms

Question

I'm trying to add an ImageComboBoxEdit control onto a UserControl within my WinForms application.
public ShortCutUserControl()
{
var imageCollection = new ImageCollection { ImageSize = new Size(48, 48) };
imageCollection.Images.Add(Image.FromFile(#"Keyboard\ctrl.ico"));
imageCollection.Images.Add(Image.FromFile(#"Keyboard\alt.ico"));
functionKeyImageComboBoxEdit.Properties.LargeImages = imageCollection;
ImageComboBoxItem ctrlItem = new ImageComboBoxItem
{
Description = "Ctrl",
ImageIndex = 0
};
ImageComboBoxItem altItem = new ImageComboBoxItem
{
Description = "Alt",
ImageIndex = 1
};
functionKeyImageComboBoxEdit.Properties.Items.Add(altItem);
functionKeyImageComboBoxEdit.Properties.Items.Add(ctrlItem);
}
When the control is loaded:
I can't change the currently either directly through code or in the UI.
functionKeyImageComboBoxEdit.SelectedIndex = 0;
I've tried attaching events to the functionKeyImageComboBoxEdit, but none of these seem to be fired/captured;
functionKeyImageComboBoxEdit.SelectedIndexChanged += FunctionKeyImageComboBoxEditOnSelectedIndexChanged;
private void FunctionKeyImageComboBoxEditOnSelectedIndexChanged(object sender, EventArgs eventArgs)
{
//throw new NotImplementedException();
}
What am I missing from my code? I've been looking at the DevExpress ImageComboBoxEdit Documentation but can't see any problem.

The cause of the issue is that you don't set values for ImageComboBoxItems. Do this like:
ImageComboBoxItem ctrlItem = new ImageComboBoxItem
{
Description = "Ctrl",
ImageIndex = 0,
Value = "Ctrl"
};
ImageComboBoxItem altItem = new ImageComboBoxItem
{
Description = "Alt",
ImageIndex = 1,
Value = "Alt"
};
