Hi,
I have a property in my user control of type Label.
Problem is if I want to set the value of the properties of this label from a host application xaml then how can it be achieved. Not able to find the correct syntax.

C#

public Label TestProperty
        {
            get { return lblValue; }
            set { lblValue = value; }
        }

in the code behind we can access this value as

C#

object.TestProperty.FontSize = 25;

how can I set the same value from the host application xaml.

Solution 1

You should implement this as a Dependency Property[^]

Solution 2

I beleive the following will help. What you need I beleive is a DependencyObject. The DependencyObject can then have DependencyProperties:

I looked into this before, and could not figure how to solve your problem. I just bypassed the problem by creating specific properties.

Well the link talk about the dependency properties and data binding. Here I want to update a property of a label exposed using a property. Still have no clue as to how can I achieve it.

Yes, after thinking about it some more, I do not think this will work because I am sure that TestProperty is a dependency object already. I am not sure what you want to do can be done without a lot of work. I know my frustration with doing something where I wanted to set properties for buttons that were part of a control.
