How do I custom sort a string column so that all the empty cells are excluded, that is, empty cells should always be at the bottom, from the GridGroupingControl?

Description

By default, empty cells are included while sorting in the GridGroupingControl. To keep these empty cells always at the bottom while sorting, you have to implement an IComparer interface.

 

Solution

This customized sorting can be done by having a user-defined class that implements the IComparer interface and writing the custom comparer code in the Compare() method. Excluding the empty cells can be done by finding the length of the string in the Compare() method and cancelling its sorting, thereby pushing the empty cells to the bottom. Refer to the following code for implementing the Compare() method.

C#

VB

You can create an instance of the SortColumnDescriptor for a particular column and set the Comparer() method to the instance of the inherited IComparer class. You can also initialize its sorting direction by using Sort Direction property.
