Not able to bind to grid
posted

Hi,

WCF webservice returning JSON Sting to UI, I am able to see data in browser, but not able to bind to grid. It is working if i assigned to string and bind to grid. 

Code below :

<script id="JsonDataTemplate" type="text/x-jquery-tmpl">

        <tr> <td> ${Description} </td> <td></tr>

 </script>

 

 $.ig.loader({

            scriptPath: '../../js/',

            cssPath: '../../css/',

            resources: 'igDataSource'

        });

 

 $.ig.loader(function () {

            BindJson();

        });

 

function BindJson() {

            $('table thead').html("<tr><th>Applies To</th></tr>");

 

            var jsonSchema = new $.ig.DataSchema("json", { fields: [

       {name: "Description", type: "string" } ]

            });

 

            url = "http://localhost:4293/DealService.svc/Get_data"; // Returning JSON String : [{ "Description": "Mock subject", "Id": 242, "Notes": "" }]

         

           // ds = new $.ig.DataSource({ dataSource: url, schema: jsonSchema, responseDataType: "json" });   tried but not working

            ds = new $.ig.DataSource({dataSource: url}); //tried not working

            // ds  = new $.ig.JSONDataSource({ dataSource: categoriesWithProducts, responseDataKey: "d" });  tried not working

 

           // ds = new $.ig.DataSource({ dataSource: jsonData });  Working with local JSON string

            ds.dataBind();

 

            $("#t1 tbody").empty();

            $("#JsonDataTemplate").tmpl(ds.dataView()).appendTo("#t1 tbody");

        }

 jsonData = [{ "Description": "Mock subject"}]; 

 

Can you please let me know. Thanks

    Hello InfraOracle ,

    The issue, that you are experiencing, happens because the databinding is still not completed when you append the dataView .

    For the purpose you do this in the callback function when data binding is complete.

    $.ig.loader().load("igGrid.*,igDataSource,igShared,igTemplating",
        function () {
            rowTemplate = "  ${ProductID}   ${Name}   ${ProductNumber} ${StandardCost}";
            url = "http://localhost:2880/AdventureWorksService.svc/Product?$format=json";
            ds = new $.ig.DataSource({
                type: "remoteUrl",
                dataSource: url,
                responseDataKey: "d",
                fields: [
                    { name: "ProductID", type: "number" },
                    { name: "Name", type: "string" },
                    { name: "ProductNumber", type: "string" },
                    { name: "StandardCost", type: "number" }
                ],
                callback: function (success, error) {
                    if (success) {
                        $("#JsonDataTemplate").tmpl(ds.dataView()).appendTo("#table1");
                    } else {
                        alert(error);
                    }
                }
            });
            ds.dataBind();
        });

    Please take a look at the help article regarding this :

    http://help.infragistics.com/NetAdvantage/jquery/2012.1?page=igDataSource_Getting_started_with_igDataSource_and_WCF.html

    More for the igDataSource options you can find in the API documentation:

    Hope this helps.
