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 ] ) );
}

Console.WriteLine(myPropertyDescriptor.Name);
Console.WriteLine(myPropertyDescriptor.GetValue
(dt.DefaultView[0]));
}

A counter used to recursively call the method.
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 );
}
}
C#
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.
