Highlighting SelectedItem from WPF Combobox to Color throws an exception

Question

I have combobox data binding to available system colors. When the user selects a color, the following code is run:

private void cboFontColour_SelectionChanged(object sender, SelectionChangedEventArgs e)
{
    Color colour = (Color)(cboFontColour.SelectedItem);
}

This throws a cast exception with the following message: "The specified cast is invalid." When I hover over cboFontColour.SelectedItem in the debugger, it is always a Color object.

I do not understand why the system, it would seem, cannot distinguish it from Color to Color, any help will be very necessary.

Answer 4

I had the same problem and none of the suggestions on this issue worked. I kept getting exceptions when I tried to use (Color), and the code didn’t even compile if I tried to use “Color”? or how". Exited the next workaround. This is not ideal, because now I need to create a new object, but at least it works:

string colorName = _comboBox.SelectedValue.ToString();
Color color = (Color)ColorConverter.ConvertFromString(colorName);
