DataReader Problem

I want to fill FlexGrid With the records returned From Executing
by SqlCommand but the problem is the FlexGrid Filled With Then
First Record Only
Is ther any way to move to next record , please advice

VB Code:

Dim mycmd As New SqlCommand("Select ItemID,ItemName,Quantity,unitPrice,Total,Remarks From Invoice_Details where InvID = " & txtInvID.Text & "", MyConn)
        MyConn.Open()
 
        Dim myReader As SqlDataReader
        myReader = mycmd.ExecuteReader
 
        Do While myReader.Read
            Dim x As Integer
            For x = 0 To Flex1.Rows - 1
                Flex1.set_TextMatrix(x, 1, myReader.GetValue(0))
                Flex1.set_TextMatrix(x, 2, myReader.GetString(1))
                Flex1.set_TextMatrix(x, 3, myReader.GetValue(2))
                Flex1.set_TextMatrix(x, 4, myReader.GetValue(3))
                Flex1.set_TextMatrix(x, 5, myReader.GetValue(4))
                Flex1.set_TextMatrix(x, 6, myReader.GetString(5))
 
            Next
 
        Loop
 
        myReader.Close()
        MyConn.Close()

I allways use DataSets for this kind of things.

I never used the DataReader myself :(

Never seen loop with a DR. Just use While and End While

While oDR.Read


End While
