javascript - Alert not working in UpdatePanel VB.Net -
here have tried.
aspx file:
<asp:updatepanel id="updatepanel1" runat="server"> <contenttemplate> <asp:button onclick="btnok1_click" id="btnok1" runat="server" text="save" /> </contenttemplate> </asp:updatepanel>
aspx.vb:
protected sub btnok1_click(sender object, e eventargs) dim alertmsg string dim alertscript string alertmsg = string.format("you selected {0}", "my message") alertscript = string.format("<script type= text/javascript>alert('{0}');</script>", alertmsg) clientscript.registerstartupscript(me.[gettype](), "alert", alertscript) end sub
i tried alert box message when clicked button (save) backend. tried solutions stackoverflow. but, codes not work me javascript alert box. event triggers fine , runs through code. me this?
the problem seems lie fact using clientscript
rather scriptmanager
.
clientscript
used synchronous postbacks, whereas scriptmanager
asycronous.
see this question more details.
