DependencyPropertyDescriptor desc = DependencyPropertyDescriptor.FromProperty( TextBox.TextProperty, typeof(TextBox)); // Use desc to get metadata information about property
DependencyPropertyDescriptor desc = DependencyPropertyDescriptor.FromProperty( TextBox.TextProperty, typeof(TextBox)); desc.AddValueChanged(textBox1, OnTextChanged); // method to handle property change event void OnTextChanged(object sender, EventArgs e) { // handle text property change here }In this example, we use the DependencyPropertyDescriptor to subscribe to the TextProperty change event of a TextBox element. This allows us to handle any changes made to the TextProperty at runtime. Overall, the DependencyPropertyDescriptor class provides a way to dynamically interact with dependency properties in a WPF element in C#. It is useful when working with UI elements and allows for more flexibility than simply defining properties in XAML.
