Custom Sorting strategy for igx grid

[Vighneshaa]

Where can I find the documentation for the custom Sorting strategy in igx?
Also, Can you provide me with the example related to custom Sorting strategy?

Hello @Vighneshaa,

The "Sorting through the API" section in the IgxGrid documentation outlines a few key aspects about providing a custom implementation of the ISortingStrategy interface.

As you can read there, "Any IgxColumnComponent or ISortingExpression can use a custom implementation of the ISortingStrategy as a substitute algorithm".

Here is a StackBlitz sample demonstrating a simple custom sort strategy applied on two columns of the IgxGrid (the initial sorting expression on the CategoryName column as well as the sortStrategy assigned to the ShipCountry column). For the purposes of the example, the sorting algorithm is altered to sort by the last symbol, in case the compared values are strings and are non-empty. Of course, you could implement any comparison logic that would be relevant to your requirement.
For reference, the implementation of the DefaultSortingStrategy can be found in the source code here.
