Hi Ahmad,

I've put together a small sample that demonstrates how you might do this using a Creation Filter. The relevant code looks like this:

public bool BeforeCreateChildElements(UIElement parent)
{
    if (parent is CaptionAreaUIElement)
    {
        // Reuse the existing FormattedTextUIElement if there's already one there
        FormattedTextUIElement childElement = parent.ChildElements.OfType<FormattedTextUIElement>().FirstOrDefault();

        if (childElement == null)
        {
            childElement = new FormattedTextUIElement(parent);
            parent.ChildElements.Add(childElement);
        }

        // In order to customize the formatted text that appears in the caption, modify this statement
        string formattedText = "<p align = \"center\">" + (parent.Control as UltraGrid).Text + "</p>";

        childElement.Value = ParsedFormattedTextValue.Parse(formattedText, ParsedFormattedTextValue.ValueType.AutoDetect, out Exception ex);
        childElement.Rect = parent.RectInsideBorders;
        return true;
    }
    return false;
}

In this sample, I'm using the formatted text to center the caption, which reproduces the effect of the original implementation. You should modify the format as per your application's needs. You can find more information about Formatting Text and what types of formatting is supported in our help.

I've attached the full sample in case you would like to see it running.
