MaterialDesignFloatingHintTextBox's Hint Always Floating above the TextBox.

[MeshkaM]

How can i make the MaterialDesignFloatingHintTextBox's Hint to stay to always float above the TextBox, regardless of whether the TextBox is empty or not.

At present there is not a simple way to achieve this without manipulating the content. This is because the internal SmartHint control uses the "empty" content to choose if it will be in the floating position (see:

MaterialDesignInXamlToolkit/MaterialDesignThemes.Wpf/SmartHint.cs

Lines 206 to 238 in 59375ff

	private void RefreshState(bool useTransitions)
	{
	IHintProxy? proxy = HintProxy;
	if (proxy is null) return;
	if (!proxy.IsVisible) return;
	var action = new Action(() =>
	{
	string state = string.Empty;
	bool isEmpty = proxy.IsEmpty();
	bool isFocused = proxy.IsFocused();
	if (UseFloating)
	state = !isEmpty || isFocused ? HintFloatingPositionName : HintRestingPositionName;
	else
	state = !isEmpty ? HintFloatingPositionName : HintRestingPositionName;
	IsHintInFloatingPosition = state == HintFloatingPositionName;
	VisualStateManager.GoToState(this, state, useTransitions);
	});
	if (DesignerProperties.GetIsInDesignMode(this))
	{
	action();
	}
	else
	{
	Dispatcher.BeginInvoke(action);
	}
	}

).

If you wanted to role your own template you could use the SmartHint control inside of the template, create your IHintProxy that always returns true for IsEmpty(). But that is likely more work than simply placing an additional TextBlock positioned where you want it.
