I need to bind a trackbar value with an integer that I have, which is constantly changing. How can I do that?

Hi aherlambang,

You need to wrap it into a class in order to use DataBinding. That class should implement INotifyPropertyChanged interface. Here is the example.
public class MyInteger : INotifyPropertyChanged
{
public event PropertyChangedEventHandler PropertyChanged;
private int intValue;
public int IntValue
{
get { return intValue; }
set
{
intValue = value;
PropertyChanged(this, new PropertyChangedEventArgs("IntValue"));
}
}

public MyInteger()
{
PropertyChanged = new PropertyChangedEventHandler(OnPropertyChanged);
intValue = 0;
}

protected void OnPropertyChanged(object send, PropertyChangedEventArgs e)
{
}
}

To use this class in DataBinding.
MyInteger myInt = new MyInteger();
myInt.IntValue = 1;
trackBar1.DataBindings.Add("Value", myInt, "IntValue");

Sincerely,
Kira Qian
