Copy Datagridview data to another Datagridview

The following is for VS2008 or higher. Place the code below into a code module, not a form or class.

<System.Runtime.CompilerServices.Extension()> _
Public Sub CloneRowWithValues(ByVal SingleRow As DataGridViewRow, ByVal Target As DataGridView)
    Dim Results As DataGridViewRow = CType(SingleRow.Clone(), DataGridViewRow)
    For Row As Int32 = 0 To SingleRow.Cells.Count - 1
        Results.Cells(Row).Value = SingleRow.Cells(Row).Value
    Next
    Target.Rows.Add(Results)
End Sub

Usage on the current row of DataGridView1 to add it to DataGridView2. Both DataGridView controls must have the same columns.

DataGridView1.CurrentRow.CloneRowWithValues(DataGridView2)

-------------------------------------------------------------------------------------------------------------------------
For copying all rows from DataGridView1 to DataGridView2
For Each row As DataGridViewRow In DataGridView1.Rows
    row.CloneRowWithValues(DataGridView2)
Next

 -------------------------------------------------------------------------------------------------------------------------
Another idea, you set a DataTable as the DataSource of a BindingSource component and set the DataSource of a DataGridView to the BindingSource. Now select some rows in the DataGridView, the code below shows how to copy the selected rows.

DataGridView1.EndEdit()
Dim TargetTable = DirectCast(bsData.DataSource, DataTable)
Dim rows = DataGridView1.SelectedRows
For Each row As DataGridViewRow In rows
    TargetTable.ImportRow(CType(bsData.Item(row.Index), DataRowView).Row)
Next

-------------------------------------------------------------------------------------------------------------------------
I tend to work from the DataTable (the DataSource) rather than the DataGridView. The above gives both approachs. You can modify the last one to exclude the BindingSource.
