Hi,

some one please help me.

XML

<zb:ZoomBoxPanel ZoomMode="FitPage" x:Name="zoomBox" Grid.Row="2" MinZoom="20" MaxZoom="300" MouseMode="Pan" WheelMode="Zoom">
         <Border BorderThickness="1" BorderBrush="Black">
             <Button Width="100" Height="200" HorizontalAlignment="Left" VerticalAlignment="Top"></Button>
         </Border>
     </zb:ZoomBoxPanel>


     <zb:ZoomBoxSlider Margin="10" Grid.Row="2" Grid.Column="0"
               HorizontalAlignment="Right" VerticalAlignment="Top"
               ZoomBox="{Binding ElementName=zoomBox}" />

the above code works fine as the both ZoomBoxPanel and ZoomBoxSlider are in same window.

but if i create one UserControl where i am going to place the ZoomBoxPanel and now the created UserControl and the ZoomBoxSlider are in same window now how can i bind the zoombox property of the ZoomBoxSlider with the ZoomBoxPanel control of the created UserControl

Thanks and regards

Not clear on what is the issue with whatever you are trying to do. BTW, looks like a 3rd party control ZoomBoxSlider - did you look at how it is used?

Hi Sandeep.

Thanks for your response. zoomboxslider is a third party control. here my doubt is not about the control. its about how to bind. as given in the above line, i want to bind the depencency property(zoombox-property) of a zoolslider-control with the child control of imageviewer.(zoombox-control is a sub control in imageviewer).

normally if both zoomslider and zoombox are in same window then <zoomboxslider zoombox="{Binding ElementName=zoomBox}"> is working fine . but if the zoomBox control is in another usercontrol placed in window then how to bind that with the dependency property of the zoom slider

You can add a property that holds the ZoomBoxPanel to your UserControl:

C#

public class MyUserControl : UserControl
{
    ...

    public ZoomBoxPanel MyZoomBox
    {
        get { return zoomBox; }
    }
    
    ...
}

and, use this property for the binding:

XML

<local:MyUserControl x:Name="myUc" ... />

<zb:ZoomBoxSlider Margin="10" Grid.Row="2" Grid.Column="0"
HorizontalAlignment="Right" VerticalAlignment="Top"
ZoomBox="{Binding ElementName=myUc, Path=MyZoomBox}" />
