Disable the postback on an ASP LinkButton

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

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

Just set href       lt asp LinkButton ID  myLink  runat  server  href     gt Click Me lt  asp LinkButton gt

This may sound like an unhelpful answer     But why are you using a LinkButton for something purely client-side  Use a standard HTML anchor tag and set its onclick action to your Javascript   If you need the server to generate the text of that link  then use an asp Label as the content between the anchor s start and end tags   If you need to dynamically change the script behavior based on server-side code  consider asp Literal as a technique   But unless you re doing server-side activity from the Click event of the LinkButton  there just doesn t seem to be much point to using it here

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

You might also want to have the client-side function return false    lt asp LinkButton runat  server  id  button  Text  Click Me  OnClick  myfunction   return false   AutoPostBack  false    gt    You might also consider    lt span runat  server  id  clickableSpan  onclick  myfunction     class  clickable  gt Click Me lt  span gt    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
