ScriptManager.RegisterClientSc...

Hi,
 
I write blew code but it dose not work.

ScriptManager.RegisterClientScriptBlock(this, this.GetType(), "imagetik", "top.$get(\"" + verifyTik.ClientID + "\").display:'block'; ", true);

And in .aspx code I set "display:none" for verifyTik.
 
I think that my question is expressive.
 
Thank you.
