DundasChart的Z-INDEX设置
DundasChart在静态模式下不用flash画图时设置Z-INDEX才有效；在动态画图模式下的Z-INDEX默认设置无效，若想有效可参考下面网址所述解决：http://support2.dundas.com/forum/tm.aspx?m=12255&mpage=1&key=⿟ 原文解决办法转述：
By default Flash objects are rendered on top of everything, so setting the z-index on a Flash object will not work. You will need to set the wmode attribute on the flash object.
To set the wmode on the Flash Chart, you will need to use the binary streaming method on the Chart. You will need two aspx pages, one for the Flash Chart and one for the main page.
On the Flash Chart page, the Chart.RenderType property would be set to BinaryStreaming and the aspx source should only contain the Chart, Register and Page tags.
On the main page, create a place holder for the Flash Chart using an Object tag with an Embed tag that points to the Flash Chart page. In the Embed tag, set the wmode attribute to transparent.
Here is a sample...
<OBJECT width="570" height="477">
<EMBED src="url of the binary streaming chart" pluginspage="http://www.macromedia.com/go/getflashplayer" width="570" height="477" type="application/x-shockwave-flash" wmode="Transparent">
</EMBED>
</OBJECT>
