Hi, I'm looking for a way to change the appearance of an UIelement.

I succesfully changed the TEXT with UICreationFilter AfterCreateChildElements but how to change the appearance to make it bold ?

public void AfterCreateChildElements(Infragistics.Win.UIElement parent)
{

(...)

if (parent is ColumnHeaderUIElement)
{
var child = parent.GetDescendant(typeof(TextUIElement)) as TextUIElement;
if (child != null)
{
if (child.Text.Contains(" - "))
{

DateTime date = DateTime.Parse(child.Text.Substring(0, child.Text.IndexOf('-')));
int weekNum = UtilsMain.getWeekNum(date.AddDays(3));
child.Text = weekNum.ToString() + " / " + date.Year;  // text changed to meet my requirements

// NEED TO CHANGE THE FONT TO MAKE IT APPEARS IN BOLD bug no child.Appearance here
}

}
