DevExpress ASP.NET 使用经验谈（9）-Dev控件客户端事件 ClientSideEvents
上一节，已经介绍了ASPxGridView的自定义列和基本事件 ，本节接着将介绍Dev控件的客户端事件模型。
在上节示例基础上，我们增加一行菜单，使用Dev的ASPxMenu来实现，如下图所示。
图一 添加菜单的界面
增加菜单的代码如下：
<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="编辑" Image-Url="~/Assets/images/menu/Edit_16x16.png" Name="edit"></dx:MenuItem>
<dx:MenuItem Text="删除" 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，它们都有一个统一的ClientSideEvents事件模型，提供控件的客户端事件支持。
此例中的ASPxMenu，如何来增加ClientSideEvents客户端事件操作呢，代码如下：
<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="编辑" Image-Url="~/Assets/images/menu/Edit_16x16.png" Name="edit"></dx:MenuItem>
<dx:MenuItem Text="删除" 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>
同时定义了Javascript方法MenuItemClick，来响应菜单项的Click事件操作：
function MenuItemClick(s, e) {
//通过e.item.name来区别由Menu的哪一项来触发
switch (e.item.name) {
case "new":
//新增操作
break;
case "edit":
//编辑操作
break;
case "delete":
//删除操作
break;
case "refresh":
//刷新操作
break;
}
}
客户端菜单项Click事件的骨架有了，如果来实现对ASPxGridView控件的上述操作呢？
此时，我们需要了解Dev控件的另外一个重要属性：ClientInstanceName，这个属性，为Dev的服务端控件提供了一个客户端的name，
定义客户端name后，ASPxGridView服务端控件，可以在客户端以客户端对象身份来进行操作和访问。
修改代码，为ASPxGridView1增加一个客户端名称："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】、【编辑】操作代码：
function MenuItemClick(s, e) {
//通过e.item.name来区别由Menu的哪一项来触发
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('请选择要编辑的记录！');
}
//编辑操作
break;
case "delete":
//删除操作
break;
case "refresh":
//刷新操作
break;
}
}
点击菜单项的【新增】，显示新增界面如下：
图二 新增界面
点击【编辑】，显示界面如下：
图三 编辑界面
注意：【新增】、【编辑】操作，分别使用了ASPxGridView客户端对象的方法：
新增行： grid.AddNewRow();
获取行索引：grid.GetFocusedRowIndex();
编辑行： grid.StartEditRow(index);
接下来，如何实现【删除】和【刷新】操作呢？这将使用Dev控件强大的Callback事件回调机制，通过客户端的PerformCallback
与服务端的CustomCallback事件回调结合，服务端的回调方法对客户端事件作出响应。
首先，我们增加服务端的Callback事件代码，选择OnCustomCallback，点击新增事件，后台代码自动完成对事件的添加：
添加事件如下：
生成的回调方法：
protected void ASPxGridView1_CustomCallback(object sender, ASPxGridViewCustomCallbackEventArgs e)
{
}
接着，继续修改MenuItemClick方法，增加对Delete事件代码：
function MenuItemClick(s, e) {
//通过e.item.name来区别由Menu的哪一项来触发
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('请选择要编辑的记录！');
}
//编辑操作
break;
case "delete":
var key = grid.GetRowKey(grid.GetFocusedRowIndex());
if (key != null && key != "") {
if (window.confirm('你确定要删除这条记录吗？')) {
grid.PerformCallback("delete@" + key);
}
}
//删除操作
break;
case "refresh":
//刷新操作
break;
}
}
继续修改服务端回调方法：
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，点击【删除】按钮，弹出删除确认对话框，点击”确定“，记录将被删除，ASPxGridView数据被刷新。
图四 点击删除，弹出确认对话框，并重新绑定数据
同理，我们实现【刷新】操作如下：
case "refresh":
grid.PerformCallback("refresh@");
//刷新操作
break;
继续修改回调方法：
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;
}
}
此时点击【刷新】按钮，数据将被刷新，如果效果不明显，可以手工修改数据库中的数据，以验证刷新的效果。
注意：【删除】操作，使用了ASPxGridView客户端对象的方法：
获取行主键：grid.GetRowKey(grid.GetFocusedRowIndex());
为了使【删除】、【刷新】操作在客户端能得到反馈，还可以在ASPxGridView的ClientSideEvents事件中增加：EndCallback，
修改服务端【删除】、【刷新】回调方法，增加如下代码：
ASPxGridView1.JSProperties.Remove("cpMsg");
ASPxGridView1.JSProperties.Add("cpMsg", "删除成功");
注意：按Dev控件约定，此处添加JSProperties的key，只能以 cp 为前缀。
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", "删除成功");
break;
case "refresh":
ASPxGridView1.DataBind();
ASPxGridView1.JSProperties.Remove("cpMsg");
ASPxGridView1.JSProperties.Add("cpMsg", "刷新成功");
break;
}
}
客户端响应EndCallback方法：
function EndCallback(s, e) {
if (s.cpMsg) {
alert(s.cpMsg);
s.cpMsg = null;
}
}
此时，再进行【删除】、【刷新】按钮完成操作时，会弹出提醒框。
图五 EndCallback 刷新返回消息
图六 EndCallback 删除返回消息
在此基础上，通过对EndCallback返回的信息进行处理，可以扩展更友好的提醒。
除了CustomCallback，还有CustomDataCallback、CustomButtonCallback，使用方法类似，细节稍有不同。
CustomDataCallback：可用于前后台的数据传输和回调。
CustomButtonCallback：可以针对特定服务端Button进行回调。
注意：对于ASPxTreeList控件，我们将使用到的客户端方法。
新增树结点： tree.StartEditNewNode();
获取树节点的主键：var key = tree.GetFocusedNodeKey();
在下一节中，将介绍ASPxTreeList的使用，到时再对CustomDataCallback，CustomButtonCallback的使用进行
详细描述。
