Hey there,

This feature seems incomplete.  I don't have the tools available in the API to get the filtering results I need.  When specifying this feature, a column setting property should include a template.  This template should return the value that the filtering feature should compare the filter against.  For instance:

I have a grid with three columns:
  - Customer Id
  - Customer Name
  - Customer Total

Configuration:
  - Customer Id is a hidden column.
  - Customer Name has a template "${CustomerId} - ${CustomerName}".
  - Filtering is enabled for all visible columns.
  - Filtering on Customer Name will only filter against Customer Name, excluding the ID which is also visible to the user.

It would be optimal to provide a column setting template where I can specify the filtering template "${CustomerId} - ${CustomerName}" so it can filter accordingly.  I do understand that I can provide a property in my data model to include a combined value of these two properties but the problem lies in complex custom data templates.  Perhaps I want to render HTML in my template.  The filtering doesn't know to exclude it.  But providing a template for filtering would provide the engine a means of understanding how to filter my results.  For instance:

$(".selector").igGrid({
  columns: [
    { key: "AccountId", dataType: "number", headerText: "Account Id" },
    { key: "Customer", dataType: "string", headerText: "Customer", template: "<input type="checkbox" value="${Customer}" data-value="${AccountId}" /> ${Customer}" }
  ],
  features: [{
    name: "Filtering",
    columnSettings: [
      { columnKey: "AccountId", allowFiltering: false },
      { columnKey: "Customer", allowFiltering: true, template: "${Customer}" }
    ]
  }]
});

As it stands, filtering would include the HTML of the checkbox when it shouldn't but there isn't a means to tell it otherwise.  Please provide us with a means.  Even if it that is an event with the current record along with its column key and index.  That would go a long ways than the current implementation.

Doooooo eeeeeet!

Thanks!
