Disable the postback on an

Question

I have an ASP.NET linkbutton control on my form. I would like to use it for javascript on the client side and prevent it from posting back to the server. (I'd like to use the linkbutton control so I can skin it and disable it in some cases, so a straight up tag is not preferred).

How do I prevent it from posting back to the server?

Answer 1

No one seems to be doing it like this:

createEventLinkButton.Attributes.Add("onClick", " if (this.innerHTML == 'Please Wait') { return false; } else {  this.innerHTML='Please Wait'; }");

This seems to be the only way that works.

Answer 2

Just set href="#"

<asp:LinkButton ID="myLink" runat="server" href="#">Click Me</asp:LinkButton>

Answer 3

I think you should investigate using a HyperLink control. It's a server-side control (so you can manipulate visibility and such from code), but it omits a regular ol' anchor tag and doesn't cause a postback.

Answer 4

Just been through this before few minutes, the correct way to do it is use

1. OnClientClick
2. Return False()

as the following example line of code:

<asp:LinkButton ID="lbtnNext" runat="server" OnClientClick="findAllOccurences(); return false();" Visible="false"/>

Just copied that line from my working code.

Answer 5

Why not use an empty ajax update panel and wire the linkbutton's click event to it? This way only the update panel will get updated, thus avoiding a postback and allowing you to run your javascript

Answer 6

use html link instead of asp link and you can use label in between html link for server side control
