自定义控件:Button

控件背景：有多个button需要有背景图片，但是wpf自带的button并没有imagebutton，如何要实现button的背景图片，需要重写template，但是如果有N个button，那需要些N个button的template，很麻烦。

所以，就有自定控件的button产生

<Grid Margin="50">

        <Grid.RowDefinitions>

            <RowDefinition Height="auto" />

            <RowDefinition Height="auto" />

        </Grid.RowDefinitions>

        <CustomControls:CommonButonn CustomText="Enable" BackgroundType="Enable" />

        <CustomControls:CommonButonn CustomText="Disable" BackgroundType="Disable" Grid.Row="1" />

    </Grid>

public class CommonButonn : Button

    {

        private ImageBrush _eBackground = new ImageBrush(new BitmapImage(new Uri("pack://application:,,,/MyCustomControls;component/Images/e_ok.png", UriKind.RelativeOrAbsolute)));

        private ImageBrush _dBackground = new ImageBrush(new BitmapImage(new Uri("pack://application:,,,/MyCustomControls;component/Images/d_ok.png", UriKind.RelativeOrAbsolute)));



        //Custom Button Label

        public string CustomText

        {

            get { return (this.Template.FindName("lbRoot", this) as Label).Content.ToString(); }

            set { (this.Template.FindName("lbRoot", this) as Label).Content = value; }

        }



        private string _backgroundType;



        public string BackgroundType

        {

            get { return _backgroundType; }

            set

            {

                _backgroundType = value;

                this.SetBackground();

            }

        }



        public CommonButonn()

        {

            this.Init();

        }



        private void Init()

        {

            ControlTemplate template = new ControlTemplate();

            FrameworkElementFactory factory = new FrameworkElementFactory(typeof(Grid), "grdRoot");

            //            factory.SetValue(BackgroundProperty, this._backGround);

            //Set Label

            FrameworkElementFactory label_factory = new FrameworkElementFactory(typeof(Label), "lbRoot");

            label_factory.SetValue(FontSizeProperty, 15.0);     //this object value is not type int

            label_factory.SetValue(ForegroundProperty, Brushes.Black);

            label_factory.SetValue(HorizontalAlignmentProperty, HorizontalAlignment.Center);

            label_factory.SetValue(VerticalAlignmentProperty, VerticalAlignment.Center);

            label_factory.SetValue(FontFamilyProperty, new FontFamily("微软雅黑"));

            factory.AppendChild(label_factory);



            template.VisualTree = factory;

            this.Template = template;

            this.ApplyTemplate();

            this.Width = 122;

            this.Height = 69;

        }



        private void SetBackground()

        {

            switch (this._backgroundType)

            {

                case "Enable":

                    (this.Template.FindName("grdRoot", this) as Grid).Background = this._eBackground;

                    break;

                case "Disable":

                    (this.Template.FindName("grdRoot", this) as Grid).Background = this._dBackground;

                    break;

            }

        }

    }
