------解决方案--------------------
1、首先将 <asp:ImageButton ID= "SearchIbtn " runat= "server " ImageUrl= "~/Images/view.gif " OnClientClick= "return showmodule(); "/>
改为：
<input type= "image " id= "SearchIbtn " src= "= "~/Images/view.gif " onclick= "return showmodule(); " />
2、然后加入这句return false;
function showmodule()
{
var Person_ID= window.showModalDialog( "DrugReceivePerson.aspx ", 'popupWindow ', "dialogWidth:450px;dialogHeight:490px; ");
if(Person_ID!=null &&Person_ID!= " " )
{
document.getElementById( 'HFPerson_ID ').value=Person_ID;
document.getElementById( "BindBtn ").click();
return false;//加入这句
}
else
{

}
}
