Assembly:

System.ComponentModel.Primitives.dll

Source:

MergablePropertyAttribute.cs

Gets a value indicating whether this property can be combined with properties belonging to other objects in a Properties window.

public:
 property bool AllowMerge { bool get(); };

public bool AllowMerge { get; }

member this.AllowMerge : bool

Public ReadOnly Property AllowMerge As Boolean

Property Value

Boolean

true if this property can be combined with properties belonging to other objects in a Properties window; otherwise, false.

Examples

The following example checks to see whether MyProperty is appropriate to merge. First the code gets the attributes for MyProperty by:

• Retrieving a PropertyDescriptorCollection with all the properties for the object.

• Indexing into the PropertyDescriptorCollection to get MyProperty.

• Saving the attributes for this property in the attributes variable.

Then the code sets myAttribute to the value of the MergablePropertyAttribute in the AttributeCollection and checks whether the property is appropriate to merge.

// Gets the attributes for the property.
AttributeCollection^ attributes = TypeDescriptor::GetProperties( this )[ "MyPropertyProperty" ]->Attributes;

// Checks to see if the property is bindable.
MergablePropertyAttribute^ myAttribute = dynamic_cast<MergablePropertyAttribute^>(attributes[ MergablePropertyAttribute::typeid ]);
if ( myAttribute->AllowMerge )
{
   // Insert code here.
}

// Gets the attributes for the property.
AttributeCollection attributes = 
   TypeDescriptor.GetProperties(this)["MyPropertyProperty"].Attributes;

// Checks to see if the property is bindable.
MergablePropertyAttribute myAttribute = (MergablePropertyAttribute)attributes[typeof(MergablePropertyAttribute)];
if(myAttribute.AllowMerge) {
   // Insert code here.
}

' Gets the attributes for the property.
Dim attributes As AttributeCollection = _
   TypeDescriptor.GetProperties(Me)("MyPropertyProperty").Attributes
       
' Checks to see if the property is bindable.
Dim myAttribute As MergablePropertyAttribute = _
   CType(attributes(GetType(MergablePropertyAttribute)), _
   MergablePropertyAttribute)
If myAttribute.AllowMerge Then
    ' Insert code here.
End If
