问题描述

我正在尝试在MVC中复制以下功能,我已经将其用于AJAX:
用户将一个项目拖放到页面上。
OnDropped会创建一个新控件并将其附加到页面上。该控件是RadDock类型的控件,它将停靠在RadDockZone类型的控件中。
旧代码:
/// <summary>
/// Creates the RadDock + Contents when dropping a graph onto the page.
/// </summary>
/// <param name=\"sender\"> The RadListBox with an element being dropped from inside it. </param>
/// <param name=\"e\"> information about the drop such as target and what is being dropped. </param>
protected void RadListBox_Dropped(object sender,RadListBoxDroppedEventArgs e)
{
CormanTradDockZone dockZone = RadDockLayout1.RegisteredZones.OfType<CormanTradDockZone>().First(registeredDockZone => registeredDockZone.ID == e.HtmlElementID);
if (!object.Equals(dockZone,null) && !dockZone.Docks.Any())
{
RadSlidingPane slidingPane = ((sender as RadListBox).Parent as RadSlidingPane);
CormantReport report = new CormantReport(int.Parse(e.sourceDragItems[0].Value),e.sourceDragItems[0].Text,slidingPane.Title);
CormanTradDock dock = new CormanTradDock(report);
dock.CreateContent();
dock.Dock(dockZone);
}
}
现在,我一直在努力思考如何在MVC中执行类似的操作。我认为应该发生的是,视图应获取必要的数据,然后将该数据传递回控制器。控制器将处理创建RadDock的操作,然后将对象转换为JSON并将数据传递回视图。检索完数据后,我相信我可以以某种方式重新创建元素,以便可以将其附加到RadDockZone,但没有Telerik.Web.UI.RadDock()构造函数...似乎完全没有希望?
这可能吗?
function OnClientDropped(sender,eventArgs) {
//Capture e.HTMLElementID,e.sourceDragItems[0].Value,and slidingPane.Title here
var droppedID = eventArgs.get_htmlElement().id;
if( droppedID.indexOf(\"RadDockZone\") != -1 )
{
var radDockZone = $find(droppedID);
//This constructor does not exist!
var radDock = new Telerik.Web.UI.RadDock();
radDock.dock(radDockZone);
}
else
{
alert(\"Failed to find RadDockZone on dropped target.\");
}
var slidingPaneTitle = \"\";
if (sender.get_id().indexOf(\"lstBxHistorical\") != -1) {
slidingPaneTitle = \"Historical Widgets\";
}
else if (sender.get_id().indexOf(\"lstBxCustom\") != -1) {
slidingPaneTitle = \"Custom Widgets\";
}
else {
alert(sender.get_id());
}
$.ajax({
type: \'POST\',url: \'ReportDropped\',dataType: \'json\',data: {
//e.HTMLElementID,etc...
},success: function (data) {
alert(\"Success\");
},errror: function (xhr,ajaxOptions,error) {
alert(\"Error\");
}
});
}
解决方法
我有它为AJAX工作:
我相信您的意思是aps.net ajax。而且,不能将asp.net的服务器控件与mvc一起使用,因为mvc根本没有任何ASP.net服务器控件严重依赖的ViewState概念。如果您确实想使用这样的控件,则有两个选择(我能想到)
实现与asp.net mvc兼容的自己的控件
或者并排运行asp.net和mvc并在需要的地方使用asp.net服务器控件
