How to disable postback on an asp Button (System.Web.UI.WebControls.Button)

Have your javascript return false when it's done.

<asp:button runat="server".... OnClientClick="myfunction(); return false;" />

.net asp.net javascript ajax

YourButton.Attributes.Add("onclick", "return false");

<asp:button runat="server" ... OnClientClick="return false" />

.net asp.net javascript ajax

You can use jquery click action and use the preventDefault() function to avoid postback

<asp:button ID="btnMyButton" runat="server" Text="MyButton" />$("#btnMyButton").click(function (e) {// some actions here e.preventDefault();}
