Question

Here is the code:

new FrameworkPropertyMetadata( (uint) 100,...

We can set in max value here as 100, is there a way to set minimum value too? Let’s say I want this default value to be between 5 and 100? I looked all over Google did not find any answers. Can anybody please suggest a solution. Thanks!

Code tried according to Reed Copsey

public static bool IsValidReading(object value)
{
    uint v = (uint)value;
    return (!v.Equals(0));
}

Full code:

public static readonly DependencyProperty Result =
            DependencyProperty.Register(
                "ResultLimit", typeof( uint ), typeof( UI ),
                new FrameworkPropertyMetadata( ( uint )10, new PropertyChangedCallback( ResultChanged ) ), IsValidReading );

The value is not the max value – it’s the default value.

There is no way to specify the min or max in the metadata directly. This should be handled via a Callback registered with the Dependency Property.
