Break out of WebForm_DoPostBackWithOptions Hell

I have been going nuts all day trying to get a link button to fire its command event and cause a postback in a GridView control.  On this particular page, whenever I click on the link, I get a WebForm_DoPostBackWithOptions instead of __doPostback, and of course I never hit the grid’s command event in my page behind.

The solution?  Set causesvalidation=”false” in the link button and the command event will fire.   Why, I don’t know, this just works and hopefully you’ll find this post before having to spend too many hours trying to figure it out.

    Figured this one out… you have validation controls with Display=”Dynamic”, causing all of your postback-triggering controls to not fire unless the input on your page is valid. Add in a ValidationGroup to only the controls you want to vaildate, as well as the button that causes the validation, then you don’t have to use the causesvalidation=”false” hack.

      This is a very interesting reply, thank you. It’s been a while since I last worked on that page, but I will certainly review it with your answer in mind. Thank you again.
