Answer 1

 <Grid x:Name="LayoutRoot" Background="White">
        <CheckBox x:Name="ChkBx" IsChecked=""></CheckBox>
        <Button IsEnabled="{Binding ElementName=ChkBx,Path=IsChecked,Mode=TwoWay}"></Button>
    </Grid>

find above code which explains binding depends upon other control.

let me know if you need more help.

Due to the lack of information I have come up with the following.

Binding b = new Binding("IsEnabled");
b.Mode = BindingMode.OneWay;
Binding bt = new Binding("TextValue");
bt.Mode = BindingMode.TwoWay;
bt.Source = this.ViewModel;

this.btnTester.SetBinding(IsEnabledProperty, b);
this.btnTester.Command = this.ViewModel.TestCommand;
this.btnTester.CommandParameter = bt;

I had a few issues with the command parameter but I did get it to work but not without tweaking. Anyways I don't recommend binding from the code behind but this is how you dot it above.

Hello Syed Amjad,

              This is possible from xaml side.. I want the same way as I was explained.code behind means from C# code, Not Xaml
