Hi All,

I am new in the Silverlight.
I want to use a combobox and HTMLHost present in the Grid in the XAML file.
Means :

I have one dropdown having some website names.

<combobox name="comboBox1" margin="0,0,265,0">
                   <comboboxitem content="Google" />
                   <comboboxitem content="Microsoft" />
                   <comboboxitem content="Code Project" />
                   <comboboxitem content="Orkut" />
                   <comboboxitem content="Facebook" />
</combobox>

and below that I have HTMLHost which will put html in XAML.

<html:HtmlHost Name="googlehtmlHost" Grid.Row="2" SourceUri=Dropdown Value  />

Now when I run my application my dropdown goes behind the HTMLHost content.

So I need the dropdown to be on front of everything.

Please help.
Thanks in Advance.

You can try changing the control's z-index to bring it up front

Solution 2

The WebBrowser control is not a silverlight object and sits on top of all content. You need to flip Visibility between the WebBrowser control and a rectangle with the fill set to WebBrowserBrush when the combobox dropdown is visible and back when it's not. something like:

XML

<WebBrowser x:Name="browserControl" Source="{Binding URL}" />
<Rectangle x:Name="browserControlRect" >
    <Rectangle.Fill>
        <WebBrowserBrush SourceName="browserControl" />
    </Rectangle.Fill>
</Rectangle>

Then either VSM, Behaviours, or code to do the toggling.

Thanks again.

So by this post I can only flip the visibility of the contents.
But is there any another way where I can normally get the dropdown on the top of everything.

Please help me out.

WebBrowser control is special but for other controls, change the Z-Index of the control you want on top.

I have a working example of how to change the Z-Index of a control from code at http://www.codeproject.com/KB/silverlight/ListDragDropSL.aspx

In this example, to change the Z-Index of a specific control, I had to remove and add the control.
