Hello

I'm trying to flip Dataset so as to flip my gridview in ASP.NET using VB.NET

I'm using this code

Public Function FlipDataSet(ByVal my_DataSet As DataSet) As DataSet
        Dim ds As New DataSet()


        For Each dt As DataTable In my_DataSet.Tables
            Dim table As New DataTable()

            For i As Integer = 0 To dt.Rows.Count
                table.Columns.Add(Convert.ToString(i))
            Next i
            Dim r As DataRow
            For k As Integer = 0 To dt.Columns.Count - 1
                r = table.NewRow()
                r(0) = dt.Columns(k).ToString()
                For j As Integer = 1 To dt.Rows.Count
                    r(j) = dt.Rows(j - 1)(k)
                Next j
                table.Rows.Add(r)
            Next k

            ds.Tables.Add(table)
        Next dt

Next time please do not post a picture but paste the error message as text. Now try i.ToString() and you should be fine.

Well it looks like you have a function - maybe an event handler for a button? - somewhere in your code called "Convert", which is confusing things...

Solution 1

You have protected method somewhere in the class that is named Convert this hides the Convert class. You can either use full namespace to tell the compiler where to find Convert:

VB

System.Convert.ToString(i)

or simply call ToString on the integer value directly:

VB

i.ToString()
