RAZOR：
Enter EmployeeID Field Value:
<input type="text" id="colValue" />
<input type="button" id="customButton" value="Change DataSource">
@(Html.EJ().Grid<EJGrid.Models.Order>("Grid")
.Datasource((IEnumerable<object>)ViewBag.datasource)
.AllowPaging()
.Columns(col =>

col.Field("OrderID").HeaderText("Order ID").TextAlign(TextAlign.Right).Width(75).Add();
col.Field("EmployeeID").HeaderText("Employee ID").TextAlign(TextAlign.Right).Width(90).Add();
col.Field("Freight").HeaderText("Freight").Format("{0:c}").TextAlign(TextAlign.Right).Width(90).Add();
col.Field("ShipCity").HeaderText("Ship City").Width(90).Add();
col.Field("Child.Test").HeaderText("TEst").Format("{0:c}").Width(90).Add();
col.Field("ShipCountry").HeaderText("Ship Country").Width(90).Add();
})
)
<script>
$("#customButton").ejButton({
size: "Normal", click: function (args) {
var obj = $("#Grid").ejGrid("instance");
var value = $("#colValue").val();
//Add custom paramter to the server
var query = new ej.Query().addParams("EmployeeID", value);
//Creating ejDataManager with UrlAdaptor

var promise = dm.executeQuery(query);
promise.done(function (e) {
