DevExpress ASP.NET 使用经验谈（9）-Dev控件客户端事件 ClientSideEvents
小編覺(jué)得挺不錯(cuò)的,現(xiàn)在分享給大家,幫大家做個(gè)參考.
上一節(jié)，已經(jīng)介紹了ASPxGridView的自定義列和基本事件 ，本節(jié)接著將介紹Dev控件的客戶端事件模型。
在上節(jié)示例基礎(chǔ)上，我們?cè)黾右恍胁藛?#xff0c;使用Dev的ASPxMenu來(lái)實(shí)現(xiàn)，如下圖所示。
????????????????????????????????????????????????????????????? 圖一 添加菜單的界面
增加菜單的代碼如下：
<dx:ASPxMenu ID="ASPxMenu1" runat="server" RenderMode="Lightweight" Width="100%" ItemAutoWidth="False" Theme="Aqua"><Border BorderWidth="0px" /><BorderTop BorderWidth="1px" /><Items><dx:MenuItem Text="新增" Image-Url="~/Assets/images/menu/Add_16x16.png" Name="new"></dx:MenuItem><dx:MenuItem Text="編輯" Image-Url="~/Assets/images/menu/Edit_16x16.png" Name="edit"></dx:MenuItem><dx:MenuItem Text="刪除" Image-Url="~/Assets/images/menu/Delete_16x16.png" Name="delete"></dx:MenuItem><dx:MenuItem Text="刷新" Image-Url="~/Assets/images/menu/Refresh_16x16.png" Name="refresh"></dx:MenuItem></Items> </dx:ASPxMenu>DevExpress ASP.NET的控件，如ASPxButton，ASPxLabel，ASPxMenu、ASPxPopupMenu、ASPxGridView、
ASPxTreeList、ASPxPopupControl等，它們都有一個(gè)統(tǒng)一的ClientSideEvents事件模型，提供控件的客戶端事件支持。
此例中的ASPxMenu，如何來(lái)增加ClientSideEvents客戶端事件操作呢，代碼如下：
<dx:ASPxMenu ID="ASPxMenu1" runat="server" RenderMode="Lightweight" Width="100%" ItemAutoWidth="False" Theme="Aqua"><Border BorderWidth="0px" /><BorderTop BorderWidth="1px" /><Items><dx:MenuItem Text="新增" Image-Url="~/Assets/images/menu/Add_16x16.png" Name="new"></dx:MenuItem><dx:MenuItem Text="編輯" Image-Url="~/Assets/images/menu/Edit_16x16.png" Name="edit"></dx:MenuItem><dx:MenuItem Text="刪除" Image-Url="~/Assets/images/menu/Delete_16x16.png" Name="delete"></dx:MenuItem><dx:MenuItem Text="刷新" Image-Url="~/Assets/images/menu/Refresh_16x16.png" Name="refresh"></dx:MenuItem></Items><ClientSideEvents ItemClick="function(s, e) {MenuItemClick(s,e);}" /></dx:ASPxMenu>?同時(shí)定義了Javascript方法MenuItemClick，來(lái)響應(yīng)菜單項(xiàng)的Click事件操作：
function MenuItemClick(s, e) {//通過(guò)e.item.name來(lái)區(qū)別由Menu的哪一項(xiàng)來(lái)觸發(fā)switch (e.item.name) {case "new"://新增操作break;case "edit"://編輯操作break;case "delete"://刪除操作break;case "refresh"://刷新操作break;} }客戶端菜單項(xiàng)Click事件的骨架有了，如果來(lái)實(shí)現(xiàn)對(duì)ASPxGridView控件的上述操作呢？
此時(shí)，我們需要了解Dev控件的另外一個(gè)重要屬性：ClientInstanceName，這個(gè)屬性，為Dev的服務(wù)端控件提供了一個(gè)客戶端的name，
定義客戶端name后，ASPxGridView服務(wù)端控件，可以在客戶端以客戶端對(duì)象身份來(lái)進(jìn)行操作和訪問(wèn)。
修改代碼，為ASPxGridView1增加一個(gè)客戶端名稱："grid"
<dx:ASPxGridView ID="ASPxGridView1" runat="server" AutoGenerateColumns="False" Width="100%"OnRowInserting="ASPxGridView1_RowInserting" ClientInstanceName="grid"OnRowUpdating="ASPxGridView1_RowUpdating"DataSourceID="XpoDataSource1" KeyFieldName="UserID" Theme="Aqua"> ...... </dx:ASPxGridView>修改MenuItemClick方法，增加【新增】、【編輯】操作代碼：
function MenuItemClick(s, e) {//通過(guò)e.item.name來(lái)區(qū)別由Menu的哪一項(xiàng)來(lái)觸發(fā)switch (e.item.name) {case "new"://新增操作grid.AddNewRow();break;case "edit":var index = grid.GetFocusedRowIndex();if (index != -1) {grid.StartEditRow(index);} else {alert('請(qǐng)選擇要編輯的記錄！');}//編輯操作break;case "delete"://刪除操作break;case "refresh"://刷新操作break;}}?點(diǎn)擊菜單項(xiàng)的【新增】，顯示新增界面如下：
???????????????????????????????????????????????????????????????????? 圖二 新增界面
點(diǎn)擊【編輯】，顯示界面如下：
??? 圖三 編輯界面
注意：【新增】、【編輯】操作，分別使用了ASPxGridView客戶端對(duì)象的方法：
新增行：????? grid.AddNewRow();
獲取行索引：grid.GetFocusedRowIndex();
編輯行：????? grid.StartEditRow(index);
?
接下來(lái)，如何實(shí)現(xiàn)【刪除】和【刷新】操作呢？這將使用Dev控件強(qiáng)大的Callback事件回調(diào)機(jī)制，通過(guò)客戶端的PerformCallback
與服務(wù)端的CustomCallback事件回調(diào)結(jié)合，服務(wù)端的回調(diào)方法對(duì)客戶端事件作出響應(yīng)。
首先，我們?cè)黾臃?wù)端的Callback事件代碼，選擇OnCustomCallback，點(diǎn)擊新增事件，后臺(tái)代碼自動(dòng)完成對(duì)事件的添加：
添加事件如下：
生成的回調(diào)方法：
protected void ASPxGridView1_CustomCallback(object sender, ASPxGridViewCustomCallbackEventArgs e){}接著，繼續(xù)修改MenuItemClick方法，增加對(duì)Delete事件代碼：
function MenuItemClick(s, e) {//通過(guò)e.item.name來(lái)區(qū)別由Menu的哪一項(xiàng)來(lái)觸發(fā)switch (e.item.name) {case "new"://新增操作grid.AddNewRow();break;case "edit":var index = grid.GetFocusedRowIndex();if (index != -1) {grid.StartEditRow(index);} else {alert('請(qǐng)選擇要編輯的記錄！');}//編輯操作break;case "delete":var key = grid.GetRowKey(grid.GetFocusedRowIndex());if (key != null && key != "") {if (window.confirm('你確定要?jiǎng)h除這條記錄嗎？')) {grid.PerformCallback("delete@" + key);}}//刪除操作break;case "refresh"://刷新操作break;} }?繼續(xù)修改服務(wù)端回調(diào)方法：
protected void ASPxGridView1_CustomCallback(object sender, ASPxGridViewCustomCallbackEventArgs e){string[] strParames = e.Parameters.ToString().Split(new char[] { '@' });switch (strParames[0]){case "delete":CriteriaOperator criteria = CriteriaOperator.Parse("[UserID]='" + strParames[1] + "'");Users obj = session.FindObject<Users>(criteria);obj.Delete();ASPxGridView1.DataBind();break;} }完成上述修改后，點(diǎn)擊【刪除】按鈕，彈出刪除確認(rèn)對(duì)話框，點(diǎn)擊”確定“，記錄將被刪除，ASPxGridView數(shù)據(jù)被刷新。
?
?????????????????????????????????????????????????????????圖四 點(diǎn)擊刪除，彈出確認(rèn)對(duì)話框，并重新綁定數(shù)據(jù)
同理，我們實(shí)現(xiàn)【刷新】操作如下：
case "refresh":grid.PerformCallback("refresh@");//刷新操作break;繼續(xù)修改回調(diào)方法：
protected void ASPxGridView1_CustomCallback(object sender, ASPxGridViewCustomCallbackEventArgs e){string[] strParames = e.Parameters.ToString().Split(new char[] { '@' });switch (strParames[0]){case "delete":CriteriaOperator criteria = CriteriaOperator.Parse("[UserID]='" + strParames[1] + "'");Users obj = session.FindObject<Users>(criteria);obj.Delete();ASPxGridView1.DataBind();break;case "refresh":ASPxGridView1.DataBind();break;}}此時(shí)點(diǎn)擊【刷新】按鈕，數(shù)據(jù)將被刷新，如果效果不明顯，可以手工修改數(shù)據(jù)庫(kù)中的數(shù)據(jù)，以驗(yàn)證刷新的效果。
注意：【刪除】操作，使用了ASPxGridView客戶端對(duì)象的方法：
獲取行主鍵：grid.GetRowKey(grid.GetFocusedRowIndex());
?
為了使【刪除】、【刷新】操作在客戶端能得到反饋，還可以在ASPxGridView的ClientSideEvents事件中增加：EndCallback，
修改服務(wù)端【刪除】、【刷新】回調(diào)方法，增加如下代碼：
ASPxGridView1.JSProperties.Remove("cpMsg");
ASPxGridView1.JSProperties.Add("cpMsg", "刪除成功");
注意：按Dev控件約定，此處添加JSProperties的key，只能以 cp 為前綴。
protected void ASPxGridView1_CustomCallback(object sender, ASPxGridViewCustomCallbackEventArgs e){string[] strParames = e.Parameters.ToString().Split(new char[] { '@' });switch (strParames[0]){case "delete":CriteriaOperator criteria = CriteriaOperator.Parse("[UserID]='" + strParames[1] + "'");Users obj = session.FindObject<Users>(criteria);obj.Delete();ASPxGridView1.DataBind();ASPxGridView1.JSProperties.Remove("cpMsg");ASPxGridView1.JSProperties.Add("cpMsg", "刪除成功");break;case "refresh":ASPxGridView1.DataBind();ASPxGridView1.JSProperties.Remove("cpMsg");ASPxGridView1.JSProperties.Add("cpMsg", "刷新成功");break;}}客戶端響應(yīng)EndCallback方法：
function EndCallback(s, e) {if (s.cpMsg) {alert(s.cpMsg);s.cpMsg = null;} }此時(shí)，再進(jìn)行【刪除】、【刷新】按鈕完成操作時(shí)，會(huì)彈出提醒框。
????????????????????????????????????????????????????????????? 圖五 EndCallback 刷新返回消息
????????????????????????????????????????????????????????????? 圖六 EndCallback 刪除返回消息
在此基礎(chǔ)上，通過(guò)對(duì)EndCallback返回的信息進(jìn)行處理，可以擴(kuò)展更友好的提醒。
?
除了CustomCallback，還有CustomDataCallback、CustomButtonCallback，使用方法類似，細(xì)節(jié)稍有不同。
CustomDataCallback：可用于前后臺(tái)的數(shù)據(jù)傳輸和回調(diào)。
CustomButtonCallback：可以針對(duì)特定服務(wù)端Button進(jìn)行回調(diào)。
注意：對(duì)于ASPxTreeList控件，我們將使用到的客戶端方法。
新增樹結(jié)點(diǎn)：?? tree.StartEditNewNode();
獲取樹節(jié)點(diǎn)的主鍵：var key = tree.GetFocusedNodeKey();
在下一節(jié)中，將介紹ASPxTreeList的使用，到時(shí)再對(duì)CustomDataCallback，CustomButtonCallback的使用進(jìn)行
詳細(xì)描述。
?
最后附上完整代碼。
