Answer 1

You can do it too

...LinkButton ID="BtnForgotPassword" runat="server" OnClientClick="ChangeText('1');return false"...

And it stop the link button postback

Answer 2

You might also want to have the client-side function return false.

<asp:LinkButton runat="server" id="button" Text="Click Me" OnClick="myfunction();return false;" AutoPostBack="false" />

You might also consider:

<span runat="server" id="clickableSpan" onclick="myfunction();" class="clickable">Click Me</span>

I use the clickable class to set things like pointer, color, etc. so that its appearance is similar to an anchor tag, but I don't have to worry about it getting posted back or having to do the href="javascript:void(0);" trick.

Answer 3

To avoid refresh of page, if the return false is not working with asp:LinkButton use

href="javascript: void;"

or

href="#"

along with OnClientClick="return false;"

<asp:LinkButton ID="linkPrint" runat="server" CausesValidation="False" href="javascript: void;"
        OnClientClick="javascript:self.print();return false;">Print</asp:LinkButton>

Above is code will call the browser print without refresh the page.

Answer 4

Have you tried to use the OnClientClick?

var myLinkButton = new LinkButton { Text = "Click Here", OnClientClick = "JavaScript: return false;" };

<asp:LinkButton ID="someID" runat="server" Text="clicky" OnClientClick="JavaScript: return false;"></asp:LinkButton>

Answer 5

In the jquery ready function you can do something like below -

var hrefcode = $('a[id*=linkbutton]').attr('href').split(':');
var onclickcode = "javascript: if`(Condition()) {" + hrefcode[1] + ";}";
$('a[id*=linkbutton]').attr('href', onclickcode);

Answer 6

In C#, you'd do something like this:

MyButton.Attributes.Add("onclick", "put your javascript here including... return false;");
