准备工作
该控件将继承基类控件UCControlBase，如果你还对UCControlBase不了解的下，
请移步 （一）c#Winform自定义控件-基类控件 查看
首先我们了解下要做的是什么，我们需要做一个可以自定义填充颜色，有圆角边框，有角标的按钮
开始
添加一个用户控件，命名为UCBtnExt ，继承 UCControlBase
先来看看我们按钮需要支持的属性吧
#region 字段属性
[Description("是否显示角标"), Category("自定义")]
public bool IsShowTips
{
get
{
return this.lblTips.Visible;
}
set
{
this.lblTips.Visible = value;
}
}
[Description("角标文字"), Category("自定义")]
public string TipsText
{
get
{
return this.lblTips.Text;
}
set
{
this.lblTips.Text = value;
}
}
private Color _btnBackColor = Color.White;
[Description("按钮背景色"), Category("自定义")]
public Color BtnBackColor
{
get { return _btnBackColor; }
set
{
_btnBackColor = value;
this.BackColor = value;
}
}
private Color _btnForeColor = Color.Black;
///
/// 按钮字体颜色
///
[Description("按钮字体颜色"), Category("自定义")]
public Color BtnForeColor
{
get { return _btnForeColor; }
set
{
_btnForeColor = value;
this.lbl.ForeColor = value;
}
}
private Font _btnFont = new System.Drawing.Font("微软雅黑", 12F, System.Drawing.FontStyle.Regular, System.Drawing.GraphicsUnit.Point, ((byte)(134)));
///
/// 按钮字体
///
[Description("按钮字体"), Category("自定义")]
public Font BtnFont
{
get { return _btnFont; }
set
{
_btnFont = value;
this.lbl.Font = value;
}
}
///
/// 按钮点击事件
///
[Description("按钮点击事件"), Category("自定义")]
public event EventHandler BtnClick;
private string _btnText;
///
/// 按钮文字
///
[Description("按钮文字"), Category("自定义")]
public string BtnText
{
get { return _btnText; }
set
{
_btnText = value;
lbl.Text = value;
}
}
#endregion
有了属性是不是就更明了呢
还有最后关键的一点东西，就是按钮的点击事件
private void lbl_MouseDown(object sender, MouseEventArgs e)
{
if (this.BtnClick != null)
BtnClick(this, e);
}
至此基本上就完工了，下面列出了完整的代码
