How to get rows collection based on selected cells in DatagridView

问题

I have a DatagridView control on a Windows form. It's selectionMode property is set to CellSelect.
I want to operate on DatagridViewRow based on selected cells. The DataGridView control is bound to a DataSource.

How to get the Row collection based on selected cells ?

回答1:

List<DataGridViewRow> rowCollection = new List<DataGridViewRow>();

foreach(DataGridViewCell cell in dataGridView.SelectedCells)
{
    rowCollection.Add(dataGridView.Rows[cell.RowIndex];
}

The answer provided as Linq does not work with the syntax provided. Datagridview does not support ienumerable so you have to use:

        IEnumerable<DataGridViewRow> selectedRows = dgPOPLines.SelectedCells.Cast<DataGridViewCell>()
                                           .Select(cell => cell.OwningRow)
                                           .Distinct();

DataGridView.SelectedCells will give you the list of cells that are selected. Each of the DataGridViewCell instances in that collection has an OwningRow, this allows you to build your own row collection.

For example:

using System.Linq;

IEnumerable<DataGridViewRow> selectedRows = dgv.SelectedCells
                                               .Select(cell => cell.OwningRow)
                                               .Distinct();
