Taking your datagridview and putting it into a dataset

[dminder]

This is a fairly short and sweet function that will take your datagridview and dump it into a dataset. This was created for/using VS 2005.

Public Function DatagridviewToDataset(ByVal dgv As DataGridView) As System.Data.DataSet
        Dim ds As New System.Data.DataSet

        'Take the data and structure from the datagridview and return it as a dataset.  You can use 
        '"Imports System.Data" declaration at the top of your project/class and remove the system.data 
        'from the various parts of this function.

        Try
            'Add a new table to the dataset
            ds.Tables.Add("Main")

            'Add the columns
            Dim col As System.Data.DataColumn

            'For each colum in the datagridveiw add a new column to your table
            For Each dgvCol As DataGridViewColumn In dgv.Columns
                col = New System.Data.DataColumn(dgvCol.Name)
                ds.Tables("Main").Columns.Add(col)
            Next

            'Add the rows from the datagridview
            Dim row As System.Data.DataRow
            Dim colcount As Integer = dgv.Columns.Count - 1

            For i As Integer = 0 To dgv.Rows.Count - 1
                row = ds.Tables("Main").Rows.Add

                For Each column As DataGridViewColumn In dgv.Columns
                    row.Item(column.Index) = dgv.Rows.Item(i).Cells(column.Index).Value
                Next

            Next

            Return ds
        Catch ex As Exception
            'Catch any potential errors and display them to the user
            MessageBox.Show("Error Converting from DataGridView" & ex.InnerException.ToString, _
            "Error Converting from DataGridView", MessageBoxButtons.OK, MessageBoxIcon.Error)
            Return Nothing
        End Try
    End Function

Edit: I flubbed the rowsetup and had to change it
