（十一）C# Winform自定義控件-列表
準(zhǔn)備工作
列表控件將被拆分為2部分，一個元素，一個列表，列表需要支持主副標(biāo)題，圖標(biāo)等
開始
首先定義一個數(shù)據(jù)源類（其實更好的是應(yīng)該接受object，然后通過綁定字段反射綁定數(shù)據(jù)，這樣就不需要這個數(shù)據(jù)源類了，這里偷懶了）
///?
///?列表實體
///?
[Serializable]
public?class?ListEntity
{
????///?
????///?編碼，唯一值
????///?
????public?string?ID?{?get;?set;?}
????///?
????///?大標(biāo)題
????///?
????public?string?Title?{?get;?set;?}
????///?
????///?右側(cè)更多按鈕
????///?
????public?bool?ShowMoreBtn?{?get;?set;?}
????///?
????///?右側(cè)副標(biāo)題
????///?
????public?string?Title2?{?get;?set;?}
????///?
????///?關(guān)聯(lián)的數(shù)據(jù)源
????///?
????public?object?Source?{?get;?set;?}
}
我們創(chuàng)建元素控件，添加一個用戶控件，命名UCListItemExt
需要提供一下屬性
[Description("標(biāo)題"),?Category("自定義")]
public?string?Title
{
????get?{?return?label1.Text;?}
????set?{?label1.Text?=?value;?}
}
[Description("副標(biāo)題"),?Category("自定義")]
public?string?Title2
{

????????label3.Visible?=?!string.IsNullOrEmpty(value);
????}
}
[Description("標(biāo)題字體"),?Category("自定義")]
public?Font?TitleFont
{
????get?{?return?label1.Font;?}
????set
????{
????????label1.Font?=?value;
????}
}
[Description("副標(biāo)題字體"),?Category("自定義")]
public?Font?Title2Font
{
????get?{?return?label3.Font;?}
????set

}
[Description("背景色"),?Category("自定義")]
public?Color?ItemBackColor

}
[Description("標(biāo)題文本色"),?Category("自定義")]
public?Color?ItemForeColor
{
????get?{?return?label1.ForeColor;?}
????set?{?label1.ForeColor?=?value;?}
}
[Description("副標(biāo)題文本色"),?Category("自定義")]
public?Color?ItemForeColor2
{
????get?{?return?label3.ForeColor;?}
????set?{?label3.ForeColor?=?value;?}
}
[Description("是否顯示右側(cè)更多箭頭"),?Category("自定義")]
public?bool?ShowMoreBtn
{
????get?{?return?label2.Visible;?}
????set?{?label2.Visible?=?value;?;?}
}
[Description("項選中事件"),?Category("自定義")]
public?event?EventHandler?ItemClick;

{
????this.Title?=?data.Title;
????this.Title2?=?data.Title2;
????this.ShowMoreBtn?=?data.ShowMoreBtn;
????DataSource?=?data;
}
#endregion
再處理一下點擊事件
private?void?item_MouseDown(object?sender,?MouseEventArgs?e)
{
????if?(ItemClick?!=?null)
????{
????????ItemClick(this,?e);
????}
}
至此功能完成，看下完整代碼

用處及效果
用處：一般用著需要橫向切換選項的地方，比如省份切換等
效果：
調(diào)用示例
List?lst?=?new?List();
for?(int?i?=?0;?i?5;?i++)
{
????lst.Add(new?ListEntity()
????{
????????ID?=?i.ToString(),
????????Title?=?"選項"?+?i,
????????ShowMoreBtn?=?true,
????????Source?=?i
????});
}
this.ucListExt1.SetList(lst);
