c# - How to create custom properties in user control? -

i have user command 2 fields:

public string offtext { set; get; } public string ontext { set; get; }

after added command in form , fill offtext , ontext properties. in control's constructor have:

public faketoggleswitch() { initializecomponent(); if (state) { checkedit.text = ontext; } else { checkedit.text = offtext; } }

and in debug mode see ontext , offtext null. whats can wrong here? have create fields?

those not fields, auto-properties.

if utilize auto-property , default value should different 0 (value type) or null (reference type), can set in constructor

public string offtext { set; get; } public string ontext { set; get; } public constructor() { // init offtext = "..."; ontext = "..."; }

otherwise may decide utilize normal properties

private string _offtext = "..."; // default value public string offtext { { homecoming _offtext; } set { _offtext = value; } }

if utilize wpf, typically usercontrol properties there have dependency properties (to back upwards binding). creating dependency property done using code snippets. type

propdp tabtab

to get

public int myproperty { { homecoming (int)getvalue(mypropertyproperty); } set { setvalue(mypropertyproperty, value); } } // using dependencyproperty backing store myproperty. enables animation, styling, binding, etc... public static readonly dependencyproperty mypropertyproperty = dependencyproperty.register("myproperty", typeof(int), typeof(ownerclass), new propertymetadata(0));
