Hi,

U need to check the OnResize event

you have to handle the resize event in siverlight whenever the Silverlight plug-in's object tag is resized and the ActualHeight or the ActualWidth of the Silverlight plug-in change.

This is specified in the HTML/ASP:

<object ...>
    ...
    <param name "onresize" value"functionname" />
    ...
</object>

when the ActualHeight or ActualWidth properties change this is fired - but when the Silverlight plugin is in full screen mode, this is not fire .

Hi,

you can refer to the code below:

        
App.Current.Host.Content.Resized += new EventHandler(Content_Resized);
        void Content_Resized(object sender, EventArgs e)
        {
            var width = App.Current.Host.Content.ActualWidth;
            var height = App.Current.Host.Content.ActualHeight;
        }

or

I think you are looking for the silverlight controls LayOutUpdated event.

thank u for ur replies. i'm sorry that i couldn't explain my problem well. indeed i need an event to be raised only when the resize gets completed. i've already tried OnResize and Resized events. they're raised whenever the size of UserControl changes like SizeChanged or LayoutUpdated. so none of these are useful.
for example in a form application we've the ResizeEnd event. we've also Resize event, but it's not useful for my purpose. in a Silverlight application we may realize whenever a control is resized by multiple ways. but my question is that how can we realize when the resize gets complete? that's when user releases the mouse left button and resize ends.
