The following code example demonstrates how to set the ColumnHeadersDefaultCellStyle, AutoSizeRowsMode, ColumnHeadersBorderStyle, CellBorderStyle, GridColor, BackgroundColor, RowHeadersVisible, SelectionMode, ColumnCount, and MultiSelect properties. In addition, the code example demonstrates how to set the DataGridViewColumn::Name and DataGridViewColumn::DefaultCellStyle properties. To run this example, paste the code into a form that contains a DataGridView named dataGridView1, and then call the SetUpDataGridView method from the form's constructor or Load event handler. Ensure all events are associated with their event handlers.
void SetUpDataGridView() { this->Controls->Add( dataGridView1 ); dataGridView1->ColumnCount = 5; DataGridViewCellStyle^ style = dataGridView1->ColumnHeadersDefaultCellStyle; style->BackColor = Color::Navy; style->ForeColor = Color::White; style->Font = gcnew System::Drawing::Font( dataGridView1->Font,FontStyle::Bold ); dataGridView1->EditMode = DataGridViewEditMode::EditOnEnter; dataGridView1->Name = "dataGridView1"; dataGridView1->Location = Point(8,8); dataGridView1->Size = System::Drawing::Size( 500, 300 ); dataGridView1->AutoSizeRowsMode = DataGridViewAutoSizeRowsMode::DisplayedCellsExceptHeaders; dataGridView1->ColumnHeadersBorderStyle = DataGridViewHeaderBorderStyle::Raised; dataGridView1->CellBorderStyle = DataGridViewCellBorderStyle::Single; dataGridView1->GridColor = SystemColors::ActiveBorder; dataGridView1->RowHeadersVisible = false; dataGridView1->Columns[ 0 ]->Name = "Release Date"; dataGridView1->Columns[ 1 ]->Name = "Track"; dataGridView1->Columns[ 1 ]->DefaultCellStyle->Alignment = DataGridViewContentAlignment::MiddleCenter; dataGridView1->Columns[ 2 ]->Name = "Title"; dataGridView1->Columns[ 3 ]->Name = "Artist"; dataGridView1->Columns[ 4 ]->Name = "Album"; // Make the font italic for row four. dataGridView1->Columns[ 4 ]->DefaultCellStyle->Font = gcnew System::Drawing::Font( DataGridView::DefaultFont,FontStyle::Italic ); dataGridView1->SelectionMode = DataGridViewSelectionMode::FullRowSelect; dataGridView1->MultiSelect = false; dataGridView1->BackgroundColor = Color::Honeydew; dataGridView1->Dock = DockStyle::Fill; dataGridView1->CellFormatting += gcnew DataGridViewCellFormattingEventHandler( this, &Form1::dataGridView1_CellFormatting ); dataGridView1->CellParsing += gcnew DataGridViewCellParsingEventHandler( this, &Form1::dataGridView1_CellParsing ); addNewRowButton->Click += gcnew EventHandler( this, &Form1::addNewRowButton_Click ); deleteRowButton->Click += gcnew EventHandler( this, &Form1::deleteRowButton_Click ); ledgerStyleButton->Click += gcnew EventHandler( this, &Form1::ledgerStyleButton_Click ); dataGridView1->CellValidating += gcnew DataGridViewCellValidatingEventHandler( this, &Form1::dataGridView1_CellValidating ); }
