Net Get Typeconverterattribute
Using Property. Grid - Code. Project. Introduction. Property. Grid is a standard component windows form, which is in the first and second version of the . NET Framework. This component allows us to display properties of practically all types of objects, without writing any additional code.
For all the demos, I created a Form and placed it on a button, with the button name btn. Assign, and Property. Grid with the name prp. G. The Simplest Way In the simplest case, you write your classes by using properties, put them on the form Property. Grid, and bind it's property Selected. Object reference to the object. You can then look in Properties.
Re: How do you set the color using hex value #6b8ec6 or the RGB. Jan 20, 2004 08:42 AM | Colt | LINK. Besides TypeConverter being slow and broken for some types, it also do not handle things such as trimming, DateTimeStyles, NumberStyles, default values, etc.
After installing Visual Studio 2012 and opening a Silverlight 5 project I'm getting various design time errors related to TypeConverter, such as: The TypeConverter. Note For XAML purposes, a XAML processor searches for the TypeConverterAttribute directly, instead of going through TypeDescriptor. For cases where you do want a. An article about using PropertyGrid in.NET; Author: witnes; Updated:; Section: Tabs & Property Pages; Chapter: Desktop Development; Updated: 7. By default, Get-Content in powershell reading the file as a one long string. which means you might have an issue if you have multiple lines of SQL statements as it.
Grid for any kind of properties of your object, writing something like this in button. Click: Property. Grid.
Simple. Demo. Class pgdc = new Property. Grid. Simple. Demo. Class(). prp. G. Selected.
Object = pgdc; So, start a new windows project, place on the form button and Property. Grid. In the property editor, assign btn. Assig name to the button, and prp. G name to Property. Grid. After this, add the new class to the solution with the following code: class Property.
Grid. Simple. Demo. Class. int m_Display. Int. publicint Display. Int. get { return m_Display. Int; }. set { m_Display. Int = value; }. string m_Display. String. publicstring Display.
String. get { return m_Display. String; }. set { m_Display.
Download source files - 7 Kb; Introduction. There have been plenty of articles here on CodeProject discussing advanced use the PropertyGrid control. Documentation about Display And Editor Templates in Extensions for ASP.NET MVC Open Source (discontinued). Get the help you need online. ASP.NET e OWIN. Nel tempo il framework ASP.NET si è trasformato. Inizialmente viveva unicamente nel contesto System.Web e le evoluzioni seguivano tempistiche di. Hi Reza, TypeConverter is a.NET class in the System.ComponentModel namespace. While you can inherit it and create your own TypeConverter, above I am using it “out.
String = value; }. Display. Bool. publicbool Display. Bool. get { return m_Display. Bool; }. set { m_Display. Bool = value; }. Color m_Display. Colors. public Color Display.
Colors. get { return m_Display. Colors; }. set { m_Display. Colors = value; }. After this, double click on the button and write the following code: Property.
Grid. Simple. Demo. Class pgdc = new Property. Grid. Simple. Demo.
Class(). prp. G. Selected. Object = pgdc; Run and compile the project, and press the button. You'll see something like this: Using Attributes in Property. Grid. In System. Component. Model, there are some useful attributes. For example: [Browsable(bool)] – to show property or not.
Read. Only(bool)] – possibility to edit property. Category(string)] – groups of property. Description(string)] – property description. It is something like a hint. Display. Name(string)] – display property.
If you use this class for assigning to Selected. Object: class Property. Grid. Simple. Demo. Class. 2. int m_Display. Int = 5. 0. [Browsable(bool)] [Read. Only(true)] [Description("sample hint.
Category("Category. Display. Name("Int for Displaying")] publicint Display.
Int. get { return m_Display. Int; }. set { m_Display. Int = value; }. string m_Display. String. [Browsable(bool)] [Read. Only(false)] [Description("Example Displaying hint 2")] [Category("Category. Display. Name("Name")] publicstring Display. String. get { return m_Display.
String; }. set { m_Display. String = value; }. Display. Bool. [Category("Category. Description("To be or not to be")] [Display.
Name("To drink or not to drink")] publicbool Display. Bool. get { return m_Display.
Bool; }. set { m_Display. Bool = value; }. Color m_Display. Colors. false)> public Color Display. Colors. get { return m_Display. Colors; }. set { m_Display. Colors = value; }. Then we get this screen: More Complex or Better Looking True/False Values - It is Especially so for Bool Values.
But sometimes, it is not enough to display just text values. Sometimes, we need a more impressive display. For example, if we want to change the variants in "To drink or not to drink" to other variants. Something like: “Yes” and “Yes, of course”. Than we need to use the attribute Type.
Converter. First of all, we should create two additional classes. First we will name Property. Grid. Simple. Demo. Class. 3, another Drinker. Class. Converter. Look at the class given below: class Property. Grid. Simple. Demo.
Class. 3. bool m_Drink. Or. Not. [Display.
Name("Drink or not")]. Description("Drink or not")]. Category("Make right decision")]. Type. Converter(typeof(Drinker.
Class. Converter))]. Drink. Or. Not. get { return m_Drink. Or. Not; }. set { m_Drink.
Or. Not = value; }. Drinker. Class. Converter : Boolean.
Converter. publicoverrideobject Convert. To(IType. Descriptor. Context context. Culture. Info culture. objectvalue. Type dest. Type).
Yes" : "Yes, of course". Convert. From(IType. Descriptor. Context context.
Culture. Info culture. Yes". }All that is needed is to use the Attribute Type. Converter, inherit Boolean. Converter, and override Convert. To and Convert. From. Then you see a result like the following: Changing Standard Way of Displaying. Imagine that you want more than two items in a list and that the boolean type is not enough.
What do you do then? First of all, you need to set the attribute Description with the needed name for every element in enum. Drink. Doses. [Description("Half of litre")]. Description("One litre")]. Description("Two litres")]. Description("Three litres")].
Litres. [Description("Four litres")]. Litres. [Description("Death dose, five litres")]. Secondly, you need to realize type Enum. Converter. class Drink. Doses. Converter: Enum. Converter. private Type _enum.
Type. public Drink. Doses. Converter(Type type).
Type = type. publicoverridebool Can. Convert. To(IType. Descriptor. Context context. Type dest. Type).
Type == typeof(string). Convert. To(IType.
Descriptor. Context context. Culture. Info culture. Type dest. Type). Field. Info fi = _enum. Type. Get. Field(Enum. Get. Name(_enum. Type, value)).
Description. Attribute dna =. Description. Attribute)Attribute.
Get. Custom. Attribute(. Description. Attribute)). Description. elsereturnvalue. To. String(). publicoverridebool Can. Convert. From(IType. Descriptor. Context context.
Type src. Type). return src. Type == typeof(string). Convert. From(IType. Descriptor. Context context.
Culture. Info culture. Field. Info fi in _enum.
Type. Get. Fields()). Description. Attribute dna =. Description. Attribute)Attribute. Get. Custom. Attribute(. Description. Attribute)). Description)). return Enum. Parse(_enum. Type, fi.
Name). return Enum. Parse(_enum. Type, (string)value).
Finally, you need to set the attribute Type. Converter for displaying a property. Drinker. Doses. Drink. Doses m_doses. [Display. Name("Doses")]. [Description("Drinker doses")].
Category("Alcoholics drinking")]. Type. Converter(typeof(Drink. Doses. Converter))]. Drink. Doses Doses. Int. publicint Data.
Int. get { return m_data. Int; }. set { m_data. Int = value; }. }So, the result should look like this: Displaying Pictures. Sometimes there arises a situation when you want to display pictures in Property. Grid. Let's say we want to show in a game Stone, scissors, paper. Then first, what do we need to organize?
We need to organize the enum, with attribute Description for every needed member: enum Game. Values. [Description("Stone")]. Description("Scissors")]. Description("Paper")]. After this, we realize Enum. Type. Converter, that converts to a stringby using the attribute Description. Game. Values. Converter: Enum.
Converter. private Type _enum. Type. public Game. Values. Converter(Type type).
Type = type. publicoverridebool Can. Convert. To(IType. Descriptor. Context context. Type dest. Type). Type == typeof(string). Convert. To(IType.
Descriptor. Context context. Culture. Info culture.
Type dest. Type). Field. Info fi = _enum. Type. Get. Field(Enum. Get. Name(_enum. Type, value)). Description. Attribute dna =. Description. Attribute) Attribute. Get. Custom. Attribute(.
Description. Attribute)). Description. elsereturnvalue. To. String(). publicoverridebool Can. Convert. From(IType. Descriptor. Context context. Type src. Type). return src. Type == typeof (string).
Convert. From(IType. Descriptor. Context context. Culture. Info culture. Field. Info fi in _enum. Type. Get. Fields()). Description. Attribute dna =. Description. Attribute) Attribute.
Get. Custom. Attribute(. Description. Attribute)). Description)). return Enum. Parse(_enum. Type, fi. Name). return Enum. Parse(_enum. Type, (string) value).
This looks very similar to the previous step. I'll show you another sample. Now we need to organize the class, which contains an element which inherits UIType.
Editor: class Game. Editor: UIType. Editor.
Get. Paint. Value. Supported(IType. Descriptor.
Context context). Paint. Value(Paint. Value. Event. Args e). Image = e. Value. To. String(). what.
Image += ". bmp". Bitmap bmp = (Bitmap)Bitmap. From. File(what. Image). Rectangle dest. Rect = e. Bounds. bmp. Make. Transparent(). e.
Graphics. Draw. Image(bmp, dest. Rect). }and bind it using attribute Editor to an editable field: class Game.
Class. Displayer. Game. Values m_Game. Values. [Display. Name("Choose your variant")]. Description("You can choose between Stone, scissors, paper")]. Category("Choosing")].
Editor(typeof(Game. Editor), typeof(UIType. Editor))]. public Game. Values Display. Game. Values. return m_Game. Values. m_Game. Values = value. After all this, you'll see: Finally I hope to hear your comments, and answer your questions.
