dropdown list event is not firing when javascript is used
- by user1511953
i have a problem in firing dropdownlist event
i have following dropdown
asp:dropdownlist id="ddlhello" Runat="server" AutoPostBack="True" onchange="javascript:return ChangeHeader();"
i have also added event in code behind i.e. selectedindex change event.
Now problem occurs when i execute the page, it executes javascript but server side code doesnot fire, but if i remove this line onchange="javascript:return ChangeHeader();" then server side code fires.
when i checked source page it shows me two onchange events associated
one for javascript and other for server side.
i think that it is picking client side code and neglects server side.
I am not pretty sure, so i want to know the behavior reason.
And what is the way out for this.
i want server and client side code to be executed.
i have searched for solutions but i have not found any correct reason.
please reply for the same. Thanks in advance
