Could not load file or assembly ‘$SharePoint.Project.AssemblyFullName$’ or one of its dependencies. The system cannot find the file specified.

There are lot of scenarios where you can face this issue. I will explain scenario which i faced.

Scenario

I have all the solution deployed and running already on the production server. My task was to just change an html link in the .ascx control. I changed the control and rather than deploying whole solution, i copied .ascx control and put it in the 14 hive control templates. I restarted IIS and refreshed page, i found following exception,

Could not load file or assembly ‘$SharePoint.Project.AssemblyFullName$’ or one of its dependencies. The system cannot find the file specified.

Solution

Luckily error was pointing towards the new custom control that i deployed. I opened file and searched for "$SharePoint.Project.AssemblyFullName$". Replace this string with the actual assembly name, version and culture (If you deploy with visual studio, it changes it automatically but as it was manual deployment, i needed to copy control's assembly and replace with the "$SharePoint.Project.AssemblyFullName$"). Restart IIS and problem was solved.

Let us start with new fresh InfoPath Library. Create an InfoPath Library and call it "AccordionForms". The path of library would be like,

Create Info Path Accordion (Show Hide Section)

Previously i worked on the project which used InfoPath form. The Form had many sections and each section had scrolling and lot of data. I needed to introduce accordion in the form. I needed to add buttons to show hide any section of the form so that user can focus on what is required. InfoPath is different than the normal JQuery accordion where you can hide or show any thing based on script or just CSS. In InfoPath you need to add behavior and Rules for each button and section which we want to hide or we want to use as changing behavior or variable. Following is the how i achieved it,

1- First thing first, add two picture buttons (Having up and down pictures).  

2- Add Boolean variable ESShow and set its default value as 0 if you want to hide section when InfoPath form loads otherwise set its default value 1.
