I am using WFFM webforms rendering with Sitecore 8.1. I don't want to do a full page reload on form post so added an update panel. The challenge is the update panel is affecting click events of another update panel. Did anyone face similar issue?


  1. Sitecore 8.1 with WFFM installed
  2. using webforms
  3. The layout has <sc:placeholder
  4. On the blog landing page added WFFM webform rendering
  5. On the same page have one other update panel for loading View More blogs.

  • Update panels do a full page postback, they just mask it behind some tricky javascript. The entire page lifecycle will run on all controls. Commented Oct 28, 2016 at 18:11

Update panels have their UpdateMode property set to Always by default, so they'll fire on any post back, even from another update panel. You'll want to set it to Conditional. Conditional will update only if a child control or child update panel is the thing triggering the post back.


  • That is true about UpdateMode. I have modified it to Conditional and started using the <Triggers> along with setting "ChildrenAsTriggers" set to false.

  • @phani Does it mean that this answer solved your problem? If it did, please mark it as accepted. If it didn't, then you'll need to clarify what else you're missing. Commented Nov 1, 2016 at 7:45
  • @Dmytro issue is not yet resolved. I will followup with the team tomorrow to understand the progress. Temporarily we are moving forward with full page reload for WFFM form to not affect the delivery timelines.
