PropertyTabAttribute()

Source:: PropertyTabAttribute.cs

Source:: PropertyTabAttribute.cs

Source:: PropertyTabAttribute.cs

Initializes a new instance of the PropertyTabAttribute class.

public:
 PropertyTabAttribute();

public PropertyTabAttribute();

Public Sub New ()

Remarks

This is a parameterless constructor that creates an uninitialized PropertyTabAttribute. This constructor can be used to derive from this attribute and specify multiple tab types by calling InitializeArrays.
