Twitter bootstrap 如何在剑道UI中使用双列表框
如何在剑道UI中创建自定义小部件?演示如何在剑道UI框架中创建自定义小部件。它还演示了如何将数据绑定到自定义小部件 您可以动态创建小部件的各种组件(ListView、按钮等),并在自定义小部件的init方法中连接事件处理程序。也就是说,您不需要将HTML与所有组件混在一起(除非您愿意)。假设您希望与ASP.NET MVC 4和剑道框架结合使用 我们将使用Razor语法和C# 首先,我们在视图中为代码编写占位符。我们将连接剑道控制和Twitter bootstrap 如何在剑道UI中使用双列表框,twitter-bootstrap,asp.net-mvc-4,c#-4.0,kendo-ui,Twitter Bootstrap,Asp.net Mvc 4,C# 4.0,Kendo Ui,如何在剑道UI中创建自定义小部件?演示如何在剑道UI框架中创建自定义小部件。它还演示了如何将数据绑定到自定义小部件 您可以动态创建小部件的各种组件(ListView、按钮等),并在自定义小部件的init方法中连接事件处理程序。也就是说,您不需要将HTML与所有组件混在一起(除非您愿意)。假设您希望与ASP.NET MVC 4和剑道框架结合使用 我们将使用Razor语法和C# 首先,我们在视图中为代码编写占位符。我们将连接剑道控制和 var urlgetcascadeMultipleSelect
var urlgetcascadeMultipleSelectBrandTypeByBrand=“@(Url.Action(“getcascadeMultipleSelectBrandTypeByBrand”,“DropDownList”))”;
@Html.LabelFor(m=>m.BrandId)
@(Html.Kendo().DropDownListFor(m=>m.BrandId)
.DataSource(source=>
{
source.Read(Read=>
{
read.Action(“GetCascadedBlandBySegment”、“DropDownList”)
.数据(“过滤器段”);
})

})

.DataValueField(“BrandId”)
.Filter(FilterType.Contains)
.CascadeFrom(“段ID”)
.OptionLabel(“选择品牌”)

.HtmlAttributes(新的{@style=“width:100%;”}))

@Html.LabelFor(m=>m.BrandTypeIdList)
@if(Model.IsEdit)
{
@Html.ListBoxFor(m=>m.BrandTypeIdList,Html.GetBrandTypeByBrandIdSelectListItemsList(Model.BrandId))
}
其他的
{
@Html.ListBoxFor(m=>m.BrandTypeIdList,new List())
}
@Html.ValidationMessageFor(m=>m.BrandTypeIdList)
然后,我们创建C#helper代码以与之配套
public static IEnumerable<SelectListItem> GetBrandTypeByBrandIdSelectListItemsList(this HtmlHelper htmlHelper, int brandId)
{
using (var dbContext = new Entities())
{
return dbContext.BrandType.Where(x => x.Active == true && x.BrandId == brandId).Select(BrandTypeToDdlSelector).ToList();
}
}
public static Func<BrandType, SelectListItem> BrandTypeToDdlSelector
{
get
{
return (x => new SelectListItem()
{
Value = x.BrandTypeId.ToString(),
Text = x.Name
});
}
}
public JsonResult GetCascadeMultiSelectBrandTypeByBrand(int? brandId)
{
var brandTypesList = DbContext.BrandType.Where(p => p.Active == true);
if (brandId != null)
{
brandTypesList = brandTypesList.Where(p => p.BrandId == brandId);
}
return Json(brandTypesList.Select(x => new { BrandTypeId = x.BrandTypeId, BrandTypeName = x.Name }), JsonRequestBehavior.AllowGet);
}
public static IEnumerable GetBrandTypeByBrandIdSelectListItemsList(此HtmlHelper HtmlHelper,int brandId)
{
使用(var dbContext=new Entities())
{
返回dbContext.BrandType.Where(x=>x.Active==true&&x.BrandId==BrandId);
}
}
公共静态函数BrandTypeToDdlSelector
{
得到
{
返回(x=>newselectListItem()
{
Value=x.BrandTypeId.ToString(),
Text=x.名称
});
}
}
public JsonResult GetCascade MultiselectBrandTypeByBrand(int?brandId)
{
var brandTypesList=DbContext.BrandType.Where(p=>p.Active==true);
if(brandId!=null)
{
brandTypesList=brandTypesList.Where(p=>p.BrandId==BrandId);
}
返回Json(brandTypesList.Select(x=>new{BrandTypeId=x.BrandTypeId,BrandTypeName=x.Name}),JsonRequestBehavior.AllowGet;
}
然后,我们创建JS代码,在运行时操作HTML,并将选定的值绑定到MVC模型
var brandTypeIdDualListbox = new Object();
$(document).ready(function ()
{
//we create the dual list control
brandTypeIdDualListbox = $('select[name="BrandTypeIdList"]').bootstrapDualListbox({
nonSelectedListLabel: 'Non-selected',
selectedListLabel: 'Selected',
preserveSelectionOnMove: 'moved',
moveOnSelect: false,
});
//we setup the change event for the control
$('select[name="BrandTypeIdList').on('change', function (args)
{
//we traverse every option
$("#BrandTypeIdList option").each(function (index,element)
{
//we check if the element has the `data-sortindex` attribute
if (!!$(element).attr('data-sortindex'))
$(element).attr('selected', 'selected');
else
$(element).removeAttr('selected');
});
})
});
function filterBrands()
{
var brandId = $("#BrandId").val();
if (brandId == "")
brandId = "-1";
return {
BrandId: brandId
};
}
function populateBrandTypeIdDualListbox()
{
$.getJSON(urlGetCascadeMultiSelectBrandTypeByBrand, filterBrands(), function (data)
{
var items;
$.each(data, function (i, item)
{
brandTypeIdDualListbox.append("<option value=" + item.BrandTypeId/*Value*/ + ">" + item.BrandTypeName/*Key or Text*/ + "</option>");
});
brandTypeIdDualListbox.trigger('bootstrapDualListbox.refresh', true); // we refresh the control
});
}
function onBrandIdDdlChange(evt)
{
var brandIdDropDownList = $("#BrandId").data("kendoDropDownList");
$('#BrandTypeIdList').empty();
brandTypeIdDualListbox.trigger('bootstrapDualListbox.refresh', true);
if ($("#BrandId").val() == "" || $("#BrandId").val() == "-1")
{
//if no value is selected we disable the control
$(".bootstrap-duallistbox-container").find("*").prop("disabled", true);
}
else
{
populateBrandTypeIdDualListbox();
$(".bootstrap-duallistbox-container").find("*").prop("disabled", false); // we enable the control
}
}
var brandTypeIdDualListbox=新对象();
$(文档).ready(函数()
{
//我们创建双列表控件
brandTypeIdDualListbox=$('select[name=“BrandTypeIdList”]”)。bootstrapDualListbox({
nonSelectedListLabel:“未选定”,
selectedListLabel:“已选”,
preserveSelectionOnMove:“已移动”,
moveOnSelect:false,
});
//我们为控件设置更改事件
$('select[name=“BrandTypeIdList')。在('change',函数(args)上
{
//我们遍历每个选项
$(“#BrandTypeIdList选项”)。每个(函数(索引,元素)
{
//我们检查元素是否具有'data sortindex'属性
if(!!$(element).attr('data-sortindex'))
$(element.attr('selected','selected');
其他的
$(元素).removeAttr('selected');
});
})
});
函数filterBrands()
{
var brandId=$(“#brandId”).val();
如果(brandId==“”)
brandId=“-1”;
返回{
布兰迪:布兰迪
};
}
函数populateBrandTypeIdDualListbox()
{
$.getJSON(urlGetCascadeMultiSelectBrandTypeByBrand,filterBrands(),函数(数据)
{
风险值项目;
$。每个(数据、功能(i、项)
{
brandTypeIdDualListbox.append(“+item.BrandTypeName/*键或Text*/+”);
});
brandTypeIdDualListbox.trigger('bootstrapDualListbox.refresh',true);//我们刷新控件
});
}
函数onBrandIDLDLChange(evt)
{
var brandIdDropDownList=$(“#BrandId”).data(“kendoDropDownList”);
$(“#BrandTypeIdList”).empty();
brandTypeIdDualListbox.trigger('bootstrapDualListbox.refresh',true);
如果($(“#BrandId”).val()=”|$(“#BrandId”).val()=“-1”)
{
//如果未选择任何值,则禁用该控件
$(“.bootstrap duallistbox容器”).find(“*”).prop(“已禁用”,true);
}
其他的
{
populateBrandTypeIdDualListbox();
$(“.bootstrap duallistbox container”).find(“*”).prop(“disabled”,false);//我们启用该控件
}
}
双列表框现在是jquery默认剑道Ui的一部分
$(document).ready(function () {
$("#optional").kendoListBox({
connectWith: "selected",
toolbar: {
tools: ["moveUp", "moveDown", "transferTo", "transferFrom", "transferAllTo", "transferAllFrom", "remove"]
}
});
$("#selected").kendoListBox();
});
