Kendo UI动态更改数据源字符串(XML)

Question

我有一个绑定到XML DataSource的Kendo Grid.如何根据下拉列表的选择更改DataSource.例:

//Create DataSource
    var gridDataSource = new kendo.data.DataSource({            
        transport: {
             read: [DropDownListValue] + ".xml",
             dataType: "xml"
        }
         });

    gridDataSource.read();

    function createGrid(){                  
            var grid = $("#grid").kendoGrid({
                dataSource: gridDataSource
                }...
             };

其中[DropDownListValue]是我表单上的下拉列表.在此示例中,如果[DropDownListValue] = 1,则数据源将为"1.xml".如果[DropDownListValue] = 2,那么数据源将是"2.xml".

我能够通过在我的下拉列表的On Change事件中添加以下内容来实现此目的:

//Assign drop down value to variable
var dropDownListValue = $("#dropDown1").val();

//Concatenate drop down variable to file name
var dynamicUrl = dropDownListValue +".xml";

//Assign grid to variable
var grid = $("#grid").data("kendoGrid");

//Set url property of the grid data source
grid.dataSource.transport.options.read.url =dynamicUrl;

//Read data source to update
grid.dataSource.read();
