準(zhǔn)備工作

該控件將繼承控件UCBtnExt，如果你還對UCBtnExt不了解的下，

請移步?（二）c#Winform自定義控件-按鈕?查看

首先我們了解下要做的是什么，我們需要做一個可以自定義填充顏色，有圓角邊框，有角標(biāo)的，有圖標(biāo)的按鈕

開始

添加一個用戶控件UCBtnImg 繼承UCBtnExt

添加屬性

private?string?_btnText?=?"自定義按鈕";
///?

///?按鈕文字
///?
[Description("按鈕文字"),?Category("自定義")]
public?new?string?BtnText
{
????get?{?return?_btnText;?}
????set
????{
????????_btnText?=?value;
????????lbl.Text?=?"????"?+?value;
????????lbl.Refresh();
????}
}
///?

///?圖片
///?
[Description("圖片"),?Category("自定義")]
public?Image?Image
{
????get
????{
????????return?this.imageList1.Images[0];
????}
????set
????{
????????this.imageList1.Images.Clear();
????????this.imageList1.Images.Add(value);
????????this.lbl.ImageIndex?=?0;
????}
}
