Question

I have two DataGridViews that have the same column schema (although two different DataViews as DataSource – if that matters). What is the best/quickest way to move a row from one datagridview to the other?

Answer 1

Even though I have two DataTable as binding for my DataGridViews, I couldn’t see any way around using the DataGridView to get the selected rows and move them, which is a requirement for my application.

GridUtility.cs

    /// <summary>
    /// Gets a list of the DataRow objects that are the datasources for a DataGridViews selected rows
    /// </summary>
    /// <param name="rows"></param>
    /// <returns></returns>
    public static DataRow[] GetSelectedDataRows(DataGridView grid)
    {   
        DataRow[] dRows = new DataRow[grid.SelectedRows.Count];
        for (int i = 0; i < grid.SelectedRows.Count; i++)
            dRows[i] = ((DataRowView)grid.SelectedRows[i].DataBoundItem).Row;

        return dRows;  
    }

    /// <summary>
    /// move row from one grid to another
    /// </summary>
    public void MoveRows(DataTable src, DataTable dest, DataRow[] rows)
    {
        foreach (DataRow row in rows)
        {   
            // add to dest
            dest.Rows.Add(row.ItemArray);

            // remove from src
            src.Rows.Remove(row);
        }
    }

To use it:

GridUtility.MoveRows(fromTable, toTable, 
    GridUtility.GetSelectedDataRows(fromDataGridView));
