Custom color does not reset color gallery selection state

[nativenolde]

Hi @batzen,

we noticed that if the selected color is set (using code) to a custom one, that is not part of the gallery items, the selection state gets not reset. as you can see below, the selection state will reset only if there is a color match:

Fluent.Ribbon/Fluent.Ribbon/Controls/ColorGallery.cs

Lines 528 to 543 in 044e23d

	foreach (var listBox in this.listBoxes)
	{
	if (isSetted == false
	&& listBox.Visibility == Visibility.Visible)
	{
	if (listBox.Items.Contains(color.Value))
	{
	listBox.SelectedItem = color.Value;
	isSetted = true;
	}
	}
	else
	{
	listBox.SelectedItem = null;
	}
	}

in our use case, we have a lot of fancy rich text content with some custom colorings, that are not introduced by the color gallery, but from external content creators using their own tooling. so let's assume a user writes some text and changes the fore color to red and moves to a fragment that has a custom fore color... then the red color gallery list-box-item is still selected, even if we set the selected color of the color gallery to the custom one.

i hope that this is an issue and not the intended behaviour, so that it can be fixed.

Sincerely yours

My workaround is to set the selected color first to null, which will reset the selection state, and then the actual (custom) color.

Will have a look and fix the issue.
