Examples

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 nameddataGridView1, 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 );

Remarks

If the ColumnHeadersBorderStyle property is set to anything other than Single, the GridColor property must be a system color.

You cannot set this property to the Custom value, which is a read-only value indicating that the border style has been customized through the use of the AdvancedColumnHeadersBorderStyle property.

Note

If visual styles are enabled for the application through the Application.EnableVisualStyles method and the EnableHeadersVisualStyles property is true, the column headers are painted using the current theme. In this case, the value of the ColumnHeadersBorderStyle property is ignored for all column headers except the TopLeftHeaderCell, to which the theme is not applied.
