緣由

????? ? 俗話說(shuō)的好："工欲善其事必先利其器"，作為軟件攻城獅也是同樣道理，攻城獅開(kāi)發(fā)的軟件目的是簡(jiǎn)化客戶的操作，讓客戶動(dòng)動(dòng)手指就可以完成很多事情，減少人力成本。這也是系統(tǒng)/軟件存在的目的。那對(duì)于攻城獅來(lái)說(shuō)怎么簡(jiǎn)化自己的操作？讓自己也動(dòng)動(dòng)手指就可以減少很多重復(fù)的工作呢？如果你對(duì)此也有同樣的疑問(wèn)或興趣，那就跟作者一起看下去吧！

????????說(shuō)到利器，自然而然的會(huì)想到宇宙第一IDE——Visual Studio 隨著版本的迭代，大大的加快了攻城獅的編碼效率。那對(duì)于我們自己開(kāi)發(fā)的軟件，如何減少重復(fù)操作，加快軟件進(jìn)度呢？這就是作者今日的主題——封裝控件。

????????作者幾年前有幸作為公司代表，到金蝶總部參觀，并學(xué)習(xí)當(dāng)年金蝶最新科技——K3 Cloud，說(shuō)實(shí)話，作者當(dāng)年年輕氣盛，和普遍技術(shù)開(kāi)發(fā)一樣，心高氣傲，對(duì)除自己研發(fā)以外的軟件不屑一顧，覺(jué)得自己才是最流P的！現(xiàn)在好了，善惡終有報(bào)，輪到自己爬著學(xué)習(xí)K3 Cloud的控件封裝來(lái)造輪子了...

????????想當(dāng)年，金戈鐵馬，氣吞萬(wàn)里如虎！....現(xiàn)如今，想起來(lái)都是淚...

????????扯遠(yuǎn)了，還是回到本篇的主題造輪子...哦，不！玩轉(zhuǎn)控件！封裝自己的插件吧！

????????今天作者主要介紹的是，封裝Dev的LabelControl和TextEdit。原因很簡(jiǎn)單，說(shuō)的好聽(tīng)就是簡(jiǎn)化自己重復(fù)操作，封裝前，拖控件大法，先拖一個(gè)LabelControl ，完善它的屬性。在拖一個(gè)TextEdit，完善它的屬性，必要時(shí)還要完善它的控件。你以為現(xiàn)在就完了嗎？不對(duì)，還要拖動(dòng)一下，看看上下左右的對(duì)齊效果....emmmmm~

實(shí)現(xiàn)

????????Talk is Cheap,Show me the Code!

????????首先我們先新建一個(gè)用戶控件，繼承UserControl，為了減少冗余代碼，作者把命名為BaseControl，后續(xù)所有用戶控件全部繼承此類。

public partial class KzxBaseControl : System.Windows.Forms.UserControl,IControl

????????其中IControl接口主要用來(lái)聲明，控件的一些屬性和事件，部分代碼如下（代碼篇幅較長(zhǎng)，有需要公眾號(hào)call我，源碼免費(fèi)贈(zèng)送）：

/// <summary>/// 控件事件委托/// </summary>/// <param name="sender">事件發(fā)起者</param>/// <param name="e">事件參數(shù)</param>public delegate void KzxControlOperateEventHandler(object sender, ControlEventArgs e);/// <summary>/// 獲取多語(yǔ)言文本事件委托/// </summary>/// <param name="sender">事件發(fā)起者</param>/// <param name="messageCode">語(yǔ)言標(biāo)識(shí)</param>/// <param name="text">多語(yǔ)言的文本</param>public delegate void KzxGetLanguageEventHandler(object sender, string messageCode, ref string text);public?interface?IControl{/// <summary>/// 有Load方法/// </summary>bool HasLoad { get; }/// <summary>/// 被引用后允許修改/// true允許,false不允許/// </summary>bool AllowEdit { get; set; }/// <summary>/// 多語(yǔ)言環(huán)境下顯示文本的對(duì)應(yīng)標(biāo)識(shí)/// </summary>string MessageCode { get; set; }/// <summary>/// 設(shè)計(jì)時(shí)的顯示，方便設(shè)計(jì)員工識(shí)別/// </summary>string DesigeCaption { get; set; }/// <summary>/// 控件的唯一標(biāo)識(shí)/// </summary>string Key { get; set; }/// <summary>/// True控件可用,False控件不可用/// </summary>Boolean Enabled { get; set; }/// <summary>/// True控件可見(jiàn),False控件不可見(jiàn)/// </summary>Boolean Visible { get; set; }/// <summary>/// Tag標(biāo)志,用于存儲(chǔ)任何數(shù)據(jù)/// </summary>object Tag { get; set; }/// <summary>/// 設(shè)計(jì)時(shí)的可用性/// </summary>Boolean DesigeEnabled { get; set; }......

????????用戶控件父類，主要集中所有用戶控件的通用屬性、方法和事件，部分代碼如下:

????????介紹完基類，我們新建在新建要給用戶控件來(lái)繼承它，并實(shí)現(xiàn)業(yè)務(wù)需求:

/// <summary>/// 文本框驗(yàn)證/// </summary>[ToolboxBitmapAttribute(typeof(Bitmap), "文本框")]public partial class KzxTextBox : KzxBaseControl

????????布局方面，應(yīng)自己要求，氣運(yùn)丹田，使出拖控件大法！

????????此處無(wú)需做任何屬性、事件設(shè)置。只需把我們?nèi)粘３Ｓ玫降膶傩浴⑹录?#xff0c;用特性標(biāo)記起來(lái)即可。部分代碼如下：

private DevExpress.XtraEditors.Controls.BorderStyles _BorderStyle = DevExpress.XtraEditors.Controls.BorderStyles.Default; /// <summary> /// 邊框顯示格式 /// </summary> [Category("數(shù)據(jù)格式"),?Description("KzxBorderStyle,邊框顯示格式"),?Browsable(true)] [McDisplayName("KzxBorderStyle")] public override DevExpress.XtraEditors.Controls.BorderStyles KzxBorderStyle {get{return this.ValueControl.Properties.BorderStyle;}set{this._BorderStyle = value;this.ValueControl.Properties.BorderStyle = value;} }/// <summary> /// 沒(méi)有多語(yǔ)言的情況下的默認(rèn)顯示標(biāo)題 /// </summary> [Category("多語(yǔ)言"), Description("DesigeCaption,沒(méi)有多語(yǔ)言的情況下的默認(rèn)顯示標(biāo)題"), Browsable(true)] [McDisplayName("DesigeCaption")] public override string DesigeCaption {get{return this.CaptionControl.Text.Trim();}set{this.CaptionControl.Text = value;} }private bool _IsNull = true; /// <summary> /// 可空性 /// </summary> [Category("驗(yàn)證"), Description("IsNull,可空性"), Browsable(true)] [McDisplayName("IsNull")] public override bool IsNull {get{SetBackColor();return this._IsNull;}set{this._IsNull = value;SetBackColor();} }/// <summary> /// 只讀性 /// </summary> [Category("驗(yàn)證"), Description("ReadOnly,只讀性"), Browsable(true)] [McDisplayName("ReadOnly")] public override bool ReadOnly {get{SetBackColor();return this.ValueControl.Properties.ReadOnly;}set{this.ValueControl.Properties.ReadOnly = value;SetBackColor();if (value == false){this.ValueControl.BackColor = Color.White;}} }private int maxLength = 0; /// <summary> /// 可錄入的最大長(zhǎng)度 /// </summary> [Category("驗(yàn)證"), Description("MaxLength,可錄入的最大長(zhǎng)度"), Browsable(true)] [McDisplayName("MaxLength")] public override int MaxLength {get{return maxLength;}set{maxLength = value;} }private Int32 _CaptionLabelWidth = 75; /// <summary> /// 顯示標(biāo)題寬度 /// </summary> [Category("外觀"), Description("CaptionLabelWidth,顯示標(biāo)題寬度"), Browsable(true)] [McDisplayName("CaptionLabelWidth")] public Int32 CaptionLabelWidth {get{return this.CaptionControl.Width;}set{this._CaptionLabelWidth = value;this.CaptionControl.Width = value;} }private string toolTipMaxLengthText = string.Empty; /// <summary> /// 數(shù)據(jù)長(zhǎng)度不能超過(guò)數(shù)據(jù)庫(kù)長(zhǎng)度提示文本 /// </summary> public override string ToolTipMaxLengthText {get { return toolTipMaxLengthText; }set { toolTipMaxLengthText = value; } }/// <summary> /// 提示信息 /// </summary> [Category("汽泡提示"), Description("ToolTipText,提示信息"), Browsable(true)] [McDisplayName("ToolTipText")] public override string ToolTipText {get{return (ValueControl == null) == true ? string.Empty : ValueControl.ToolTip;}set{if (ValueControl != null){ValueControl.ToolTip = value;}if (CaptionControl != null){CaptionControl.ToolTip = value;}} }private string _ToolTipMessageCode = string.Empty; /// <summary> /// 提示多語(yǔ)言標(biāo)識(shí) /// </summary> [Category("汽泡提示"), Description("ToolTipMessageCode,提示信息多語(yǔ)言標(biāo)識(shí)"), Browsable(true)] [McDisplayName("ToolTipMessageCode")] public override string ToolTipMessageCode {get{return this._ToolTipMessageCode;}set{this._ToolTipMessageCode = value;} }

????????一起看看用戶控件效果以及封裝的屬性事件：

????????F5看看運(yùn)行效果：

????? ?Done! 一個(gè)控件，減少一半操作量！?在此，本控件當(dāng)作作者拋磚引玉，看官們可以根據(jù)自己實(shí)際情況進(jìn)行數(shù)據(jù)封裝。有效的封裝，避免畫(huà)蛇添足哦~

????????最后，由于后續(xù)所有重寫(xiě)/重繪控件都在同一個(gè)項(xiàng)目使用，而且Dev系統(tǒng)引用文件較多，壓縮后源碼文件仍然很大，如果有需要源碼的朋友，可以微信公眾號(hào)聯(lián)系博主，源碼可以免費(fèi)贈(zèng)予~！有疑問(wèn)的也可以CALL我一起探討，最最后，如果覺(jué)得本篇博文對(duì)您或者身邊朋友有幫助的，麻煩點(diǎn)個(gè)關(guān)注！贈(zèng)人玫瑰，手留余香，您的支持就是我寫(xiě)作最大的動(dòng)力，感謝您的關(guān)注，期待和您一起探討！再會(huì)！
