Exemplos

O exemplo a seguir cria um DataGridTextBoxColumn e adiciona-o GridColumnStylesCollection ao de um DataGrid. Para executar este exemplo de código, cole-o em um formulário que tenha um DataGrid nome dataGrid1 e chame-o do construtor do Form.

private:
   void AddColumn()
   {
      DataTable^ myTable = gcnew DataTable;
      
      // Add a new DataColumn to the DataTable.
      DataColumn^ myColumn = gcnew DataColumn( "myTextBoxColumn" );
      myColumn->DataType = System::Type::GetType( "System::String" );
      myColumn->DefaultValue = "default string";
      myTable->Columns->Add( myColumn );
      
      // Get the CurrencyManager for the DataTable.
      CurrencyManager^ cm = dynamic_cast<CurrencyManager^>(this->BindingContext[ myTable ]);
      
      // Use the CurrencyManager to get the PropertyDescriptor for the new column.
      System::ComponentModel::PropertyDescriptor^ pd = cm->GetItemProperties()[ "myTextBoxColumn" ];
      DataGridTextBoxColumn^ myColumnTextColumn;
      
      // Create the DataGridTextBoxColumn with the PropertyDescriptor.
      myColumnTextColumn = gcnew DataGridTextBoxColumn( pd );
      
      // Add the new DataGridColumn to the GridColumnsCollection.
      dataGrid1->DataSource = myTable;
      dataGrid1->TableStyles->Add( gcnew DataGridTableStyle );
      dataGrid1->TableStyles[ 0 ]->GridColumnStyles->Add( myColumnTextColumn );
   }

private void AddColumn()
{
     DataTable myTable= new DataTable();
 
     // Add a new DataColumn to the DataTable.
     DataColumn myColumn = new DataColumn("myTextBoxColumn");
     myColumn.DataType = System.Type.GetType("System.String");
     myColumn.DefaultValue="default string";
     myTable.Columns.Add(myColumn);
     // Get the CurrencyManager for the DataTable.
     CurrencyManager cm = (CurrencyManager)this.BindingContext[myTable];
     // Use the CurrencyManager to get the PropertyDescriptor for the new column.
     PropertyDescriptor pd = cm.GetItemProperties()["myTextBoxColumn"];
     DataGridTextBoxColumn myColumnTextColumn;
     // Create the DataGridTextBoxColumn with the PropertyDescriptor.
     myColumnTextColumn = new DataGridTextBoxColumn(pd);
     // Add the new DataGridColumn to the GridColumnsCollection.
     dataGrid1.DataSource= myTable;
     dataGrid1.TableStyles.Add(new DataGridTableStyle());
     dataGrid1.TableStyles[0].GridColumnStyles.Add(myColumnTextColumn);
 }

Private Sub AddColumn()
    Dim myTable As New DataTable()
    
    ' Add a new DataColumn to the DataTable.
    Dim myColumn As New DataColumn("myTextBoxColumn")
    myColumn.DataType = System.Type.GetType("System.String")
    myColumn.DefaultValue = "default string"
    myTable.Columns.Add(myColumn)
    ' Get the CurrencyManager for the DataTable.
    Dim cm As CurrencyManager = CType(Me.BindingContext(myTable), CurrencyManager)
    ' Use the CurrencyManager to get the PropertyDescriptor for the new column.
    Dim pd As PropertyDescriptor = cm.GetItemProperties()("myTextBoxColumn")
    Dim myColumnTextColumn As DataGridTextBoxColumn
    ' Create the DataGridTextBoxColumn with the PropertyDescriptor.
    myColumnTextColumn = New DataGridTextBoxColumn(pd)
    ' Add the new DataGridColumn to the GridColumnsCollection.
    dataGrid1.DataSource = myTable
    dataGrid1.TableStyles.Add(New DataGridTableStyle())
    dataGrid1.TableStyles(0).GridColumnStyles.Add(myColumnTextColumn)
End Sub

Comentários

A DataGridTextBoxColumn classe deriva da abstract classe DataGridColumnStyle. Em tempo de execução, os DataGridTextBoxColumn hosts hospedam um DataGridTextBox controle que permite aos usuários editar texto.

As propriedades especiais adicionadas à classe incluem Formate HideEditBox. Essas propriedades permitem que você acesse o controle hospedado DataGridTextBox e seus atributos e defina o formato para exibir valores.

Se a fonte de dados for um DataTable objeto que DataColumn contém, a DataType propriedade deve ser definida como um tipo de DataColumn dados que pode ser editado logicamente em um controle de caixa de texto. Os seguintes tipos de dados são automaticamente associados a: DataGridTextBoxColumnByte, , DateTime, Decimal, Double, Int16, , Int32, Int64, UInt16, , UInt32, UInt64, , Single, e String.
