Connecting to Web Service

In this topic, we will show how to bind a DataBound control to a WebService using the RadClientDataSourceControl.

• From the Toolbox in Visual Studio, drag a RadClientDataSource instances to the design surface of your page.

• Set a WebService using the Url property. In this example we are using "http://demos.telerik.com/kendo-ui/service/Northwind.svc/Products"

<telerik:RadClientDataSource ID="RadClientDataSource1" runat="server">
    <DataSource>
        <WebServiceDataSourceSettings ServiceType="OData">
            <Select Url="http://demos.telerik.com/kendo-ui/service/Northwind.svc/Products" DataType="JSONP" />
        </WebServiceDataSourceSettings>
    </DataSource>
</telerik:RadClientDataSource>

• Configure the Model Schema and set the Fileds for the data source control

<telerik:RadClientDataSource ID="RadClientDataSource1" runat="server">
    <DataSource>
        <WebServiceDataSourceSettings ServiceType="OData">
            <Select Url="http://demos.telerik.com/kendo-ui/service/Northwind.svc/Products" DataType="JSONP" />
        </WebServiceDataSourceSettings>
    </DataSource>
    <Schema>
        <Model>
            <telerik:ClientDataSourceModelField FieldName="ProductName" DataType="String" />
            <telerik:ClientDataSourceModelField FieldName="QuantityPerUnit" DataType="String" />
            <telerik:ClientDataSourceModelField FieldName="UnitPrice" DataType="Number" />
            <telerik:ClientDataSourceModelField FieldName="UnitsInStock" DataType="Number" />
            <telerik:ClientDataSourceModelField FieldName="Discontinued" DataType="Boolean" />
        </Model>
    </Schema>
</telerik:RadClientDataSource>

• Assign the ClientDataSource to the DataBound control.

• The DataBound control will properly retrieve the data from the WebService
