Ii. Bind WPF to object data sources of various data sources

Front-end code:

  <Window.Resources>        <Con:BackgroundConverter x:Key="BackgroundConverter"/>    </Window.Resources>

Bind an object data source with listview

<Listview Height = "262" margin =, 310 "verticalalignment =" bottom "itemssource =" {binding} "name =" listview2 "horizontalalignment =" right "width =" "> <listview. view> <gridview> <gridviewcolumn header = "no." displaymemberbinding = "{binding Path = ID}" width = "100"/> <gridviewcolumn header = "name" displaymemberbinding = "{ binding Path = Name} "width =" 100 "/> <gridviewcolumn header =" Age "width =" 100 "> <gridviewcolumn. celltemplate> <datatemplate> <textblock grid. column = "1" text = "{binding Path = age}" foreground = "{binding Path = age, converter = {staticresource backgroundconverter} "/> </datatemplate> </gridviewcolumn. celltemplate> </gridviewcolumn> </gridview> </listview. view> </listview>

　　

Background code:

 public class BackgroundConverter : IValueConverter    {        #region IValueConverter Members        public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)        {            Color color = new Color();            int num = int.Parse(value.ToString());            if (num > 100)                color = Colors.Yellow;            else if (num < 50)                color = Colors.LightGreen;            else                color = Colors.LightPink;            return new SolidColorBrush(color);        }        public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)        {            throw new NotImplementedException();        }        #endregion    }

Below is the person class

 public class Person    {        private string _ID;        private string _name;        private string _age;        public string ID        {            get;            set;        }        public string Name        {            get;            set;        }        public int Age        {            get;            set;        }    }

// The following figure shows the data source. Of course, the data source can be the data read from the database. You can create a data source directly here.

// Create a data source. You can also obtain the data source private ilist <person> getpersoninfo () {ilist <person> plist = new list <person> () from the database (); for (INT I = 40; I <60; I ++) {person P = new person (); p. id = "ID" + I; p. name = "nmae" + I; p. age = I + 1; plist. add (p) ;}return plist ;}public window1 () {initializecomponent (); listview2.datacontext = getpersoninfo ();}

2. Another way to use Object

    <Window.Resources>        <Con:BackgroundConverter x:Key="BackgroundConverter"/>        <ObjectDataProvider x:Key="myPerson" ObjectType="{x:Type Con:Person}"  MethodName="getPersonInfo"/>    </Window.Resources>

In this case, the myperson object data source is the getpersoninfo method in the person class.

([Supplement] If getpersoninfo is in different class libraries, use the following method:

   <ObjectDataProvider x:Key="myPerson2" ObjectType="{x:Type ClassLibrary1:Person}"  MethodName="getPersonInfo"/>

Classlibrary1 is the name of the class library. And add a namespace

 xmlns:ClassLibrary1="clr-namespace:ClassLibrary1;assembly=ClassLibrary1"

)

<Listview Height = "262" margin =, 310 "datacontext =" {staticresource myperson} "verticalignment =" bottom "itemssource =" {binding} "name =" listview2 "horizontalalignment =" right "width =" "> <listview. view> <gridview> <gridviewcolumn header = "no." displaymemberbinding = "{binding Path = ID}" width = "100"/> <gridviewcolumn header = "name" displaymemberbinding = "{ binding Path = Name} "width =" 100 "/> <gridviewcolumn header =" Age "width =" 100 "> <gridviewcolumn. celltemplate> <datatemplate> <textblock grid. column = "1" text = "{binding Path = age}" foreground = "{binding Path = age, converter = {staticresource backgroundconverter} "/> </datatemplate> </gridviewcolumn. celltemplate> </gridviewcolumn> </gridview> </listview. view> </listview>
