WPF后台代码实现TextBlock滚动条

 

方法一：

常规的wpf操作：

        <scrollviewer width="300" height="150" borderbrush="brown" borderthickness="2" verticalscrollbarvisibility="auto" horizontalscrollbarvisibility="auto">
            <textblock x:name="_txtb" background="hotpink" textwrapping="wrap" foreground="wheat"/>
        </scrollviewer>

后台代码：

_txtb.text = "1\r\n7\r\n6\r\n5dsaadsfjhduhtndsadjdhsajhscadsadsadas哈哈哈你\r\n4\r\n3\r\n2\r\n1\r\n0\r\n1\r\n2";

 

方法二：

后台直接写：       

        public mainwindow()
　　　　　{
            initializecomponent();

            var outer = new scrollviewer();
            outer.background = brushes.gray;
            outer.width = 300;
            outer.height = 100;

            var inner = new textblock();
            inner.background = brushes.orange;
            inner.foreground = brushes.white;
            inner.width = 200;

            outer.content = inner;
            outer.maxheight = 80;

            inner.text = "1\r\n7\r\n6\r\n5dsaadsfjhduhtndsadjdhsajhscadsadsadas哈哈哈你\r\n4\r\n3\r\n2\r\n1\r\n0\r\n1\r\n2";

            // 此行用于文本内容根据设定宽度，当一行过长时自动换行
            // inner.textwrapping = textwrapping.wrap;

            outer.verticalscrollbarvisibility = scrollbarvisibility.auto;
            outer.horizontalscrollbarvisibility = scrollbarvisibility.auto;

            // 此句慎用呀，此处主要为了在界面上显示出结果
            this.content = outer;
        }
