DataGridColumnStyle(PropertyDescriptor)

Initializes a new instance of the DataGridColumnStyle class with the specified PropertyDescriptor.

public:
 DataGridColumnStyle(System::ComponentModel::PropertyDescriptor ^ prop);

public DataGridColumnStyle (System.ComponentModel.PropertyDescriptor prop);

new System.Windows.Forms.DataGridColumnStyle : System.ComponentModel.PropertyDescriptor -> System.Windows.Forms.DataGridColumnStyle

Public Sub New (prop As PropertyDescriptor)

Parameters

prop

PropertyDescriptor

A PropertyDescriptor that provides the attributes for the column.

Examples

The following code example creates a new DataGridTextBoxColumn (derived from DataGridColumnStyle) and adds it to the GridColumnStylesCollection of a DataGridTableStyle.

void CreateNewDataGridColumnStyle()
{
   DataSet^ myDataSet = gcnew DataSet( "myDataSet" );
   
   // Insert code to populate the DataSet.
   // Get the CurrencyManager for the table you want to add a column to.
   CurrencyManager^ myCurrencyManager = dynamic_cast<CurrencyManager^>(this->BindingContext[myDataSet, "Suppliers"]);
   
   // Get the PropertyDescriptor for the DataColumn.
   PropertyDescriptor^ pd = myCurrencyManager->GetItemProperties()[ "City" ];
   
   // Construct the DataGridColumnStyle with the PropertyDescriptor.
   DataGridColumnStyle^ myColumn = gcnew DataGridTextBoxColumn( pd );
   myColumn->MappingName = "City";
   dataGrid1->TableStyles[ 0 ]->GridColumnStyles->Add( myColumn );
}

private void CreateNewDataGridColumnStyle(){
  DataSet myDataSet = new DataSet("myDataSet");
   // Insert code to populate the DataSet.
    
   // Get the CurrencyManager for the table you want to add a column to.
  CurrencyManager myCurrencyManager = 
  (CurrencyManager)this.BindingContext[myDataSet, "Suppliers"];

  // Get the PropertyDescriptor for the DataColumn.
  PropertyDescriptor pd = myCurrencyManager.GetItemProperties()["City"];

   // Construct the DataGridColumnStyle with the PropertyDescriptor.
  DataGridColumnStyle myColumn = new DataGridTextBoxColumn(pd);
  myColumn.MappingName = "City";
  dataGrid1.TableStyles[0].GridColumnStyles.Add(myColumn);
}

Private Sub CreateNewDataGridColumnStyle()
   Dim myDataSet As New DataSet("myDataSet")
   ' Insert code to populate the DataSet.

   ' Get the CurrencyManager for the table you want to add a column to.
   Dim myCurrencyManager As CurrencyManager = CType _
   (Me.BindingContext(myDataSet.Tables("Suppliers")), CurrencyManager)

   ' Get the PropertyDescriptor for the DataColumn.
   Dim pd As PropertyDescriptor = _
   myCurrencyManager.GetItemProperties()("City")

   ' Construct the DataGridColumnStyle with the PropertyDescriptor.
   Dim myColumn As New DataGridTextBoxColumn(pd)
   myColumn.MappingName = "City"
   dataGrid1.TableStyles(0).GridColumnStyles.Add(myColumn)

End Sub

Remarks

To create a new DataGridColumnStyle, you must first get the CurrencyManager for the data source of the table to which the column will be added. See the CurrencyManager and BindingManager for details on getting specific CurrencyManager objects for a form.

From the CurrencyManager, you can then get the PropertyDescriptor for the DataColumn that will supply the data for the column.

When you create an instance of a DataGridColumnStyle, the following read/write properties are initialized.

Property	Initial value
Alignment	HorizontalAlignment.Left
DataGridTableStyle	null
FontHeight	-1
Invalidate	false
NullText	"(null)"
ReadOnly	false
