Property Value

Type: System.Windows.Forms::ContextMenuStrip^

The ContextMenuStrip associated with the current DataGridViewColumn. The default is null.

The shortcut menu appears when a user clicks the right mouse button in the column's display area.

The following code example uses the ContextMenuStrip property to add functionality for changing a cell's background color.

ToolStripMenuItem^ toolStripItem1;
void AddContextMenu()
{
   toolStripItem1->Text = L"Redden";
   toolStripItem1->Click += gcnew EventHandler( this, &DataGridViewColumnDemo::toolStripItem1_Click );
   System::Windows::Forms::ContextMenuStrip^ strip = gcnew System::Windows::Forms::ContextMenuStrip;
   IEnumerator^ myEnum = dataGridView->Columns->GetEnumerator();
   while ( myEnum->MoveNext() )
   {
      DataGridViewColumn^ column = safe_cast<DataGridViewColumn^>(myEnum->Current);
      column->ContextMenuStrip = strip;
      column->ContextMenuStrip->Items->Add( toolStripItem1 );
   }
}

DataGridViewCellEventArgs^ mouseLocation;

// Change the cell's color.
void toolStripItem1_Click( Object^ /*sender*/, EventArgs^ /*args*/ )
{
   dataGridView->Rows[ mouseLocation->RowIndex ]->Cells[ mouseLocation->ColumnIndex ]->Style->BackColor = Color::Red;
}


// Deal with hovering over a cell.
void dataGridView_CellMouseEnter( Object^ /*sender*/, DataGridViewCellEventArgs^ location )
{
   mouseLocation = location;
}
