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。
