C#自定义控件—文本显示、文本设值
C#用户控件之文本显示、设定组件如何绘制一个便捷的文本显示组件、文本设值组件(TextShow,TextSet)?
绘制此控件的目的就是方便一键搞定标签显示(可自定义方法显示文本颜色等),方便自定义方法又省略了挨个拖拽的过程
纯定义属性
【文本设定】:字体、标签、值、单位;事件方法:Enter、Leave、KeyDown
【文本显示】:变量名称、变量值、单位、字体、控件刻度
直接上代码
【文本设定】
public partial class TextSet : UserControl
{
public TextSet()
{
InitializeComponent();
this.txt_Value.ReadOnly = true;
}
#region 属性字体、标签、值、单位
