BindingManagerBase.GetItemProperties Method

Definition

Gets the list of property descriptors for the data source.

Overloads

GetItemProperties()

When overridden in a derived class, gets the collection of property descriptors for the binding.

GetItemProperties(ArrayList, ArrayList)

Gets the collection of property descriptors for the binding using the specified ArrayList.

GetItemProperties(Type, Int32, ArrayList, ArrayList)

Gets the list of properties of the items managed by this BindingManagerBase.

GetItemProperties()

When overridden in a derived class, gets the collection of property descriptors for the binding.

public:
 abstract System::ComponentModel::PropertyDescriptorCollection ^ GetItemProperties();
public abstract System.ComponentModel.PropertyDescriptorCollection GetItemProperties ();
abstract member GetItemProperties : unit -> System.ComponentModel.PropertyDescriptorCollection
Public MustOverride Function GetItemProperties () As PropertyDescriptorCollection

Returns

A PropertyDescriptorCollection that represents the property descriptors for the binding.

Examples

The following code example uses the GetItemProperties method to return a PropertyDescriptorCollection. The example prints the Name and value of the current DataColumn using the GetValue method of the PropertyDescriptor.

void ShowGetItemProperties()
{
   
   // Create a new DataTable and add two columns.
   DataTable^ dt = gcnew DataTable;
   dt->Columns->Add( "Name", Type::GetType( "System.String" ) );
   dt->Columns->Add( "ID", Type::GetType( "System.String" ) );
   
   // Add a row to the table.
   DataRow^ dr = dt->NewRow();
   dr[ "Name" ] = "Ann";
   dr[ "ID" ] = "AAA";
   dt->Rows->Add( dr );
   PropertyDescriptorCollection^ myPropertyDescriptors = this->BindingContext[ dt ]->GetItemProperties();
   PropertyDescriptor^ myPropertyDescriptor = myPropertyDescriptors[ "Name" ];
   Console::WriteLine( myPropertyDescriptor->Name );
   Console::WriteLine( myPropertyDescriptor->GetValue( dt->DefaultView[ 0 ] ) );
}

private void ShowGetItemProperties()
{
   // Create a new DataTable and add two columns.
   DataTable dt = new DataTable();
   dt.Columns.Add("Name", Type.GetType("System.String"));
   dt.Columns.Add("ID", Type.GetType("System.String"));
   // Add a row to the table.
   DataRow dr = dt.NewRow();
   dr["Name"] = "Ann";
   dr["ID"] = "AAA";
   dt.Rows.Add(dr);

   PropertyDescriptorCollection myPropertyDescriptors = 
   this.BindingContext[dt].GetItemProperties();
   PropertyDescriptor myPropertyDescriptor = 
   myPropertyDescriptors["Name"];
   Console.WriteLine(myPropertyDescriptor.Name);
   Console.WriteLine(myPropertyDescriptor.GetValue
   (dt.DefaultView[0]));
}

Private Sub ShowGetItemProperties()
   ' Create a new DataTable and add two columns.
   Dim dt As New DataTable()
   dt.Columns.Add("Name", Type.GetType("System.String"))
   dt.Columns.Add("ID", Type.GetType("System.String"))
   ' Add a row to the table.
   Dim dr As DataRow = dt.NewRow()
   dr("Name") = "Ann"
   dr("ID") = "AAA"
   dt.Rows.Add(dr)
     
   Dim myPropertyDescriptors As PropertyDescriptorCollection = _
   Me.BindingContext(dt).GetItemProperties()
   Dim myPropertyDescriptor As PropertyDescriptor = myPropertyDescriptors("Name")
   Console.WriteLine(myPropertyDescriptor.Name)
   Console.WriteLine(myPropertyDescriptor.GetValue(dt.DefaultView(0)))
End Sub

GetItemProperties(ArrayList, ArrayList)

Gets the collection of property descriptors for the binding using the specified ArrayList.

protected public:
 virtual System::ComponentModel::PropertyDescriptorCollection ^ GetItemProperties(System::Collections::ArrayList ^ dataSources, System::Collections::ArrayList ^ listAccessors);
protected internal virtual System.ComponentModel.PropertyDescriptorCollection GetItemProperties (System.Collections.ArrayList dataSources, System.Collections.ArrayList listAccessors);
abstract member GetItemProperties : System.Collections.ArrayList * System.Collections.ArrayList -> System.ComponentModel.PropertyDescriptorCollection
override this.GetItemProperties : System.Collections.ArrayList * System.Collections.ArrayList -> System.ComponentModel.PropertyDescriptorCollection
Protected Friend Overridable Function GetItemProperties (dataSources As ArrayList, listAccessors As ArrayList) As PropertyDescriptorCollection

Parameters

dataSources
ArrayList

An ArrayList containing the data sources.

listAccessors
ArrayList

An ArrayList containing the table's bound properties.

Returns

A PropertyDescriptorCollection that represents the property descriptors for the binding.

Remarks

This method is used by developers creating data-bound controls.

GetItemProperties(Type, Int32, ArrayList, ArrayList)

Gets the list of properties of the items managed by this BindingManagerBase.

protected:
 virtual System::ComponentModel::PropertyDescriptorCollection ^ GetItemProperties(Type ^ listType, int offset, System::Collections::ArrayList ^ dataSources, System::Collections::ArrayList ^ listAccessors);
protected virtual System.ComponentModel.PropertyDescriptorCollection GetItemProperties (Type listType, int offset, System.Collections.ArrayList dataSources, System.Collections.ArrayList listAccessors);
abstract member GetItemProperties : Type * int * System.Collections.ArrayList * System.Collections.ArrayList -> System.ComponentModel.PropertyDescriptorCollection
override this.GetItemProperties : Type * int * System.Collections.ArrayList * System.Collections.ArrayList -> System.ComponentModel.PropertyDescriptorCollection
Protected Overridable Function GetItemProperties (listType As Type, offset As Integer, dataSources As ArrayList, listAccessors As ArrayList) As PropertyDescriptorCollection

Parameters

listType
Type

The Type of the bound list.

offset
Int32

A counter used to recursively call the method.

dataSources
ArrayList

An ArrayList containing the data sources.

listAccessors
ArrayList

An ArrayList containing the table's bound properties.

Returns

A PropertyDescriptorCollection that represents the property descriptors for the binding.

Examples

The following code example uses the GetItemProperties method to return a PropertyDescriptorCollection for a BindingManagerBase. The example then prints out the Name and PropertyType of each PropertyDescriptor in the collection.

void PrintPropertyDescriptions( BindingManagerBase^ b )
{
   Console::WriteLine( "Printing Property Descriptions" );
   PropertyDescriptorCollection^ ps = b->GetItemProperties();
   for ( int i = 0; i < ps->Count; i++ )
   {
      Console::WriteLine( "\t{0}\t{1}", ps[ i ]->Name, ps[ i ]->PropertyType );

   }
}

private void PrintPropertyDescriptions(BindingManagerBase b)
{
   Console.WriteLine("Printing Property Descriptions");
   PropertyDescriptorCollection ps = b.GetItemProperties();
   for(int i = 0; i < ps.Count; i++)
   {
      Console.WriteLine("\t" + ps[i].Name + "\t" + ps[i].PropertyType);
   }
}

Private Sub PrintPropertyDescriptions(b As BindingManagerBase)
    Console.WriteLine("Printing Property Descriptions")
    Dim ps As PropertyDescriptorCollection = b.GetItemProperties()
    Dim i As Integer
    For i = 0 To ps.Count - 1
        Console.WriteLine((ControlChars.Tab & ps(i).Name & ControlChars.Tab & ps(i).PropertyType.ToString))
    Next i
End Sub

Remarks

This overload is used by developers to create data-bound controls.
