让silverlight不在最顶层，可以在悬浮层之下

方法是在Asp.net 调用页面的object中增加Windowless="true"参数即可。即增加下行代码。

<param name="Windowless" value="true" />

整个Object代码如下：

 <object data="data:application/x-silverlight-2," type="application/x-silverlight-2"
                width="100%" height="100%">
                <param name="source" value="../ClientBin/Iaddtech.Environmental.Web.Silverlight.xap" />
                <param name="onError" value="onSilverlightError" />
                <param name="background" value="white" />
                <param name="minRuntimeVersion" value="3.0.40818.0" />
                <param name="onLoad" value="siliverLoaded" />
                <param name="autoUpgrade" value="true" />
                <param name="Windowless" value="true" />
                <a href="http://go.microsoft.com/fwlink/?LinkID=149156&v=3.0.40818.0" style="text-decoration: none">
                    <img src="http://go.microsoft.com/fwlink/?LinkId=108181" alt="Get Microsoft Silverlight"
                        style="border-style: none" />
                </a>
            </object>
