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

Same functionality, less overhead

Nevertheless, your issue is that OnCheckedChanged is a server side event, and it requires a server side function. You need to put the event for a html control in there, if you want to call on the client side. OR if there's an OnClientCheckedChanged, call that and make sure it returns false so no server side event is called.

Hi dharam,

Use (ClientScript.RegisterClientScriptBlock).It is useful for calling client side code.
