![]() Public static bool operator =(HourMinute Hm1, HourMinute Hm2) Return new HourMinute(Hm1._Hour - Hm2._Hour, Hm1._Minute - Hm2._Minute) Public static HourMinute Subtract(HourMinute Hm1, HourMinute Hm2) Return new HourMinute(Hm1._Hour + Hm2._Hour, Hm1._Minute + Hm2._Minute) Public static HourMinute Add(HourMinute Hm1, HourMinute Hm2) Public static HourMinute operator -(HourMinute Hm1, HourMinute Hm2) Public static HourMinute operator +(HourMinute Hm1, HourMinute Hm2) Public static implicit operator SizeF(HourMinute Hm) Public static readonly HourMinute Empty = new HourMinute( 0, 0) Now we need to organize the class, which contains an element which inherits UITypeEditor: This looks very similar to the previous step. ![]() (DescriptionAttribute) Attribute.GetCustomAttribute( Return Enum.Parse(_enumType, ( string) value) įinally, you need to set the attribute TypeConverter for displaying a property. If ((dna != null) & (( string) value = dna.Description)) Public override bool CanConvertFrom(ITypeDescriptorContext context,įoreach (FieldInfo fi in _enumType.GetFields()) (DescriptionAttribute)Attribute.GetCustomAttribute( Public override bool CanConvertTo(ITypeDescriptorContext context,įieldInfo fi = _enumType.GetField(Enum.GetName(_enumType, value)) / Initializing instance /// type Enum /// this is only one function, that you must What do you do then? First of all, you need to set the attribute Description with the needed name for every element in enum. Imagine that you want more than two items in a list and that the boolean type is not enough. Then you see a result like the following: Changing Standard Way of Displaying Public override object ConvertFrom(ITypeDescriptorContext context,Īll that is needed is to use the Attribute TypeConverter, inherit BooleanConverter, and override ConvertTo and ConvertFrom. ![]() Public override object ConvertTo(ITypeDescriptorContext context, Look at the class given below:Ĭlass DrinkerClassConverter : BooleanConverter First we will name PropertyGridSimpleDemoClass3, another DrinkerClassConverter. First of all, we should create two additional classes. Than we need to use the attribute TypeConverter. Something like: “Yes” and “Yes, of course”. For example, if we want to change the variants in "To drink or not to drink" to other variants. Sometimes, we need a more impressive display. Then we get this screen: More Complex or Better Looking True/False Values - It is Especially so for Bool Valuesīut sometimes, it is not enough to display just text values. that is a question public bool DisplayBoolįalse)> // this property should be hidden public Color Displa圜olors and more than Display String public string DisplayString I want to say more, than just DisplayInt public int DisplayInt Int m_DisplayInt = 50 // some initialization
