yang DataGridViewCellStyle mewakili gaya tampilan sel yang sedang diformat. Defaultnya adalah nilai properti sel InheritedStyle .

Contoh

Contoh kode berikut menunjukkan cara menggunakan properti untuk mewarnai CellStyle latar belakang sel yang berisi string "Pink" ke Pink.

void dataGridView1_CellFormatting( Object^ /*sender*/, DataGridViewCellFormattingEventArgs^ e )

   // If the column is the Artist column, check the
   // value.

      {
         // Check for the string "pink" in the cell.
         String^ stringValue = dynamic_cast<String^>(e->Value);
         stringValue = stringValue->ToLower();
         if ( (stringValue->IndexOf( "pink" ) > -1) )
         {
            DataGridViewCellStyle^ pinkStyle = gcnew DataGridViewCellStyle;

            //Change the style of the cell.

Keterangan

Mengatur properti objek yang dikembalikan oleh CellStyle properti akan mengubah cara sel dan kontennya ditampilkan. Untuk menghindari penalti performa, gunakan properti ini untuk mengubah gaya sel daripada mengakses sel secara langsung.
