Filtering DynamicContent items on Frontend
I am running into Validation of viewstate MAC failed errors when trying to follow this example.
If I enter a value into the city text box and click the search button I receive the validation of viewstate MAC failed error. I have paging turned on and I noticed that if I go to a different page other than the default page #1 that the search feature appears to work fine. It is just on this initial page that it fails.
Things I have checked:
1.) There is not action value set on my masterpage <form> tag. It reads <form id="mainForm" runat="server">
2.) I enabled viewstate from Titles & Properties for the page in question
I have created custom forms in the past and have not had to generate a machine key so this feels like something else going on, but any input would be helpful.
I do not get this error if I use a template that is based on Sitefinity's UI and not MasterPage.
I have narrowed it down to being an issue with one of my MVC widgets that is on the template. I am using nested templates based off a masterpage so when I base the page off just the master it does not have an issue, but once I base it off one of the nested templates with my MVC widgets it starts to have issues.
If I figure it out I'll update everyone.
So the culprit is that I decorated my controller action with
[OutputCache(NoStore = true, Duration = 0)]
I need to have the MVC widget not cache on the page, but I do not want to disable caching for the page entirely. I am aware that Sitefinity has some wrappers to setup cache substitution, but I have not used them before and am not sure how I should go about addressing this.
Any suggestions on what I could do to invalidate caching for an MVC widget that will not break the page when using custom filtering?
