C# 클래스 FundraisingMenu.SearchServices.FundraisingMenuSearchServices

Get a function to pass into a LINQ OrderBy clause. The column sorting parameter is an index that gives the index of the column to sort by in display order. The list of columns is also in display order. So, we have to get the name of the column to sort by looking it up in the list of columns at the specified sort column index. Then, we can look up the attribute by name in the dataMap and return a lambda expression.

Retrieves all Hub projects with the Fundraising Flag set to true.

Add "virtual" projects for any packages that don't have any associated projects. The search capability is data driven by *projects* and all package information is derived from projects. Therefore to show a package with no associated projects, we need to add at least one project record that corresponds to each package. This function accomplishes that. This is an ugly solution to the problem, but I considered many alternatives and they were all uglier or required a huge rework of how the page works. Since we're not sure exactly how this is all going to shake out anyway, this seemed like the most cost-effective solution for now.

Duplicate records by package entry. This ensures we will see one project entry per package relationship and that every package is displayed on the front end.

Retrieve the Project and its related Package data needed for a result row for the specified Project.

Order menu records. This function always orders first by package.

We need to use a more advanced paging strategy because there are virtual records that will not be displayed in the table. So instead of using the start and length arguments from the query as a hard Skip/Take boundary, we need to count how many virtual records preceeded the current page and we need to take records up to the query length, but excluding virtual records from the count.
