在VB.NET中将一个datagridview数据传输到另一个datagridview

Question

Issue: Moving multiple rows and columns from one datagridview(non-data bound) to another datagridview and then displaying the second datagridview rows from another form which is data bound.

Developing platform : VB.NET 2008

Issue description:

• I have some rows and columns in another form's datagridview which is now populated from a local database that is now connected in my application.
• Having an error in EncodingCompleteDataSet inside the Update argument, which says 'Error 1 'EncodingCompleteDataSet' is a type and cannot be used as an expression.'
• Where would I insert anotherForm.Show() in the following code?

Issue Code:

Dim dr = DirectCast(DataGridViewX1.Rows(e.RowIndex).DataBoundItem, System.Data.DataRowView).Row
frmEncodeDatabase.EncodingCompleteDataSet.Tables("EncodingComplete").ImportRow(dr)
EncodingCompleteDataSetTableAdapters.EncodingCompleteTableAdapter.Update(EncodingCompleteDataSet, "EncodingComplete")

EDIT: For Jason Faulkner

Code:

For Each Col As DataGridViewColumn In DataGridViewX1.Columns
        frmEncodeDatabase.EncodingCompleteDataGridView.Columns.Add(DirectCast(Col.Clone, DataGridViewColumn))
    Next
    frmEncodeDatabase.EncodingCompleteDataGridView.Rows.Add(DataGridViewX1.Rows(0).Cells.Cast(Of DataGridViewCell).Select(Function(c) c.Value).ToArray)

Your code (which I altered a little):

Dim table As DataTable = DirectCast(frmEncodeDatabase.EncodingCompleteDataGridView.DataSource, DataView).Table

    ' Add row 0 to the DataGridViewX1 grid to the table.
    ' This assumes the schema/column names are the same between the two.
    Dim addRow As DataRow = table.NewRow
    For Each Col As DataGridViewColumn In DataGridViewX1.Columns
        addRow(Col.Clone) = frmEncodeDatabase.EncodingCompleteDataGridView.Rows(0).Cells(Col.Clone).Value
    Next

    ' Add the copied row values to the table.
    ' Once we do this, it should appear in the EncodingCompleteDataGridView.
    table.Rows.Add(addRow)

But I'm having an error in table As DataTable = DirectCast(frmEncodeDatabase.EncodingCompleteDataGridView.DataSource, DataView).Table which says

InvalidCastException was unhandled: Unable to cast object of type 'System.Windows.Forms.BindingSource' to type 'System.Data.DataView'.

Answer 1

'This is your new DataGridView

 Dim grdNew As New DataGridView



'This adds the row to your newDataGridView

    For Each item In Me.DataGridView1.Rows

        grdNew.Rows.Add(item)

    Next
