Thank you for the step-by-step response. However, when I try enabling client binding, I get an error saying that I am missing 

Infragistics.Web.UI.GridControls.WebDataGrid.js_obf.igWebDataGridClientBinding.js

I then tried the code with that commented it out and it runs through the code successfully but does not display anything in the grid.

NOTE: Since your solution required the grid's _applyClientBinding() function that is not available in the 10.3 release, I had to grab it off the samples page. The code runs through without error, but I am not sure if there are any other functions that are necessary.

Hello bpg730,

Thank you for your interest regarding ClientBinding.

In order to use it you should :

1)       Include the JQuery scripts:

<script src="Scripts/jquery-1.4.2.js" type="text/javascript"></script>

    <script src="Scripts/jquery.tmpl.js" type="text/javascript"></script>

2)       Set EnableClientRendering = true in the code behind:

this.WebDataGrid1.EnableClientRendering = true;

3)       Set any datasource to the WebDataGrid. It can be an empty list :

 this.WebDataGrid1.EnableClientRendering = true;

                  List<Product> list = new List<Product>();

                  this.WebDataGrid1.DataSource = list;

4)       Set json array as a datasource  on the client side. In this sample I am using Initialize client event for the purpose.

You can add items to the json with push function.

function Initialize(sender, args) {

            var grdPipeline = $find('<%=WebDataGrid1.ClientID%>');

            var jsonString = { "PipeLineNoteEntry":

             [{ "Product_ID": "117", "Product_Name": "Luyba", "Unit_Price": "123.56" },

             { "Product_ID": "118", "Product_Name": "Radoslav", "Unit_Price": "345.56" },

             { "Product_ID": "119", "Product_Name": "Tsvetelina", "Unit_Price": "456.56" },

             { "Product_ID": "120", "Product_Name": "Hristo", "Unit_Price": "567.56" },

             { "Product_ID": "121", "Product_Name": "Vladimir", "Unit_Price": "678.56"}

             ]

            };

            var dataSource = grdPipeline._get_dataSource();

            var arr = jsonString.PipeLineNoteEntry;

            for (var i = 0; i < arr.length; i++) {

                dataSource.push(jsonString.PipeLineNoteEntry[i]);

            }

            grdPipeline._set_dataSource(dataSource);

            grdPipeline._pi.show(grdPipeline);

            grdPipeline._applyClientBinding();

            grdPipeline._pi.hide(grdPipeline);

        }

The client binding functionality is CTP and it is not still supported officially in 10.3 version.

Let us know if you need further assistance.

I have been looking at this example, but it appears as though it is calling methods not available in 10.3. Specifically, I am getting an error on the grid._applyClientBinding() line. Is there an updated version or hotfix that has these methods for the WebDataGrid?
