Grouping by Code

Question

I have created a Table within SQL Server Report Builder, and the first field is a calculated field with the following code:
=Code.ChangeWord(Fields!NAME.Value)
Where the function is
Public Function ChangeWord(ByVal s As String) As String   Dim strBuilder As New System.Text.StringBuilder(s) If s.Contains("ESI  ") Then      strBuilder.Replace(s,"ESI")      Return strBuilder.ToString()      Else : Return s   End IfEnd Function
Now, when I execute this, it works beautifully ... except that the Grouping mechanism doesn't group all instances of "ESI" together, like I want it to.
How do I change this behavior so that it groups all instances of "ESI" together, like it should?

Hi DonFord81,
Per my understanding that you have add the custom code to convert the values in the fields which contails "ESI " to "ESI" and then add group on this fields, but the group not work, right?
I have tested on my local environment and can't reproduce the issue, as Prasad  mentioned that please make sure you are using below expression on the group like below:
=Code.ChangeWord(Fields!NAME.Value)
You can not use the custom code but just create an calculated field using the expression like below and then use the Calculated field to create the group as Prasad mentioned:
=IIF(Left(Fields!Name.Value,4)="ESI ","ESI",Fields!Name.Value)

If your problem still exists, please try to provide more details information.
