How To Stop Ajax Post Back when A button contains OnClick() and onclientclick events November 28, 2008
Posted by venkatworld in Uncategorized.trackback
When A button Contains Two event functions ,one on client side and the other on Server side, The Page posts back event occurs even when the page not pass the validation.
To Avoid this unwanted postback ,we should explicitly call
the method
Page_ClientValidate() in the javascript event method or function.
Here is the Example:
<
asp:ImageButton ID=”imgBtnSubmit” CssClass=”image” ValidationGroup=”Submit” onclientclick=”javascript:if(Page_ClientValidate())return HaspopUpClosed(); “ OnClick=”imgBtnSubmit_Clicked” runat=”server” ImageUrl=”~/res/images/img/Updatebtn.jpg” />
