).

为什么会这样..请尽快帮助我

解决方案

MS IntelliSense可能不会显示它，但是由于您检查了每个单击，尝试使用"OnClick = AlterChildren()"代替OnCheckChanged. 我在测试函数内部使用了一个简单的"alert"命令测试了该解决方案，并且效果很好.

如果您的复选框除了调用客户端函数外什么也不做，为什么您是否要通过服务器端事件来做到这一点?

使用类似

< INPUT TYPE ="checkbox" ID ="chkAnmelder"   VALUE ="1" CHECKED ="false"  onClick =">  ; 

功能相同，开销较少

解决方案

MS IntelliSense might not show it, but since your checking on every click, try the "OnClick=AlterChildren()" instead of OnCheckChanged. I tested this solution with a simple "alert" command inside of a test function, and it worked fine.

If your checkbox does nothing but call a client-side function, why are you trying to do it with a server-side event?

use something like 

<INPUT TYPE="checkbox" ID="chkAnmelder" VALUE="1" CHECKED="false"  onClick="AlterChildren()">  

Same functionality, less overhead 

Its client''s desire to convert all the html controls into asp controls..
