Dim strSQL6 As String = "select * from (select Regno, FeeType,SName, AmountPaid,Class from FeeTrans)FeeTrans PIVOT(Sum(AmountPaid) for [FeeType] in (' + VFeeType + ')) as AP where Class='" & cboClass.Text & "'"
        Dim DaAp6 As New SqlDataAdapter(strSQL6, con)
        Dim Dset6 As New DataTable
        DaAp6.Fill(Dset6)
        DataGridView2.DataSource = Dset6

1. What error?
2. You need to be clear on what output format you are expecting data
3. Is PIVOT really needed?

First of all, using SELECT * in pivot table is wrong! Pivot tables need to use at least one column to produce rows and at least one (or more) column that produced column-headers.
More about pivots here:
http://msdn.microsoft.com/en-US/library/ms177410%28v=sql.105%29.aspx[^]
http://archive.msdn.microsoft.com/SQLExamples/Wiki/View.aspx?title=PIVOTData[^]

Secondly, NEVER do it in a code! Use stored procedure on a server side.

Probably, your stored procedure should looks like:

SQL

CREATE PROCEDURE GetMyPivot()
    @class NVARCHAR(20)

AS
BEGIN

DECLARE @cols NVARCAHR(200)
			
SET @col = STUFF((SELECT DISTINCT '],[' + [FeeType] 
                 FROM FeeMaster1
                 ORDER BY '],[' + [FeeType]
                 FOR XML PATH('')),1,2,'') + ']' 

SELECT [Regno], [SName], [Class], @cols
FROM (
      SELECT [Regno], [FeeType], [SName], [AmountPaid], [Class] 
      FROM FeeTrans
     ) AS DT
PIVOT(SUM([AmountPaid]) FOR [FeeType] IN (@cols)) as PT 
WHERE [Class]=@class 

END
