How to pass additional parameter to server-side in ASP.NET Web Forms Grid?

1 min read

This Knowledge base explains how to pass additional parameters to server side while performing CRUD operations in Grid.


This can be achieved using actionBegin event of ejGrid. In this event when edited record is saved the value is passed to the controller using “addParams” property of query API of ejGrid.


1.Render the grid control


<div id="Grid"></div>
var records= ej.dataManager.Raw(Json.Encode(Viewbag.dataSource));
<script type="text/javascript">
        $(function () {
         dataSource: ej.DataManager({ json: records, adaptor: new ej.remoteSaveAdaptor(), updateUrl:"Home/NormalUpdate", insertUrl:"Home/NormalInsert",removeUrl: "Home/NormalDelete" }),
           allowPaging: true,
           editSettings: { allowEditing: true, allowAdding: true, allowDeleting: true},
           toolbarSettings: { showToolbar: true, toolbarItems: ["add","edit","delete", "update","cancel"]},
             columns: [
                            { field: "OrderID", headerText: "Order ID", isPrimaryKey: true, width:” 80” },
                            { field: "EmployeeID", headerText: "Employee ID", width:” 80”},
                            { field: "CustomerID", headerText: "Customer ID", width:” 70” },
                            { field: "ShipCountry", headerText: "Ship Country", width:” 70” },



                     .Datasource(ds => ds.Json((IEnumerable<object>)ViewBag.dataSource).UpdateURL("/Home/NormalUpdate").InsertURL("/Home/NormalInsert").RemoveURL("/Home/NormalDelete").Adaptor(AdaptorType.RemoteSaveAdaptor))
             .EditSettings(edit => { edit.AllowEditing().AllowAdding().AllowDeleting();})
            .ToolbarSettings(toolbar =>
                toolbar.ShowToolbar().ToolbarItems(items =>
                        .Columns(col =>
                    col.Field("OrderID").IsPrimaryKey(true).HeaderText("Order ID").Width(80).Add();
                    col.Field("EmployeeID").HeaderText("Employee ID").Width(80).Add();
                    col.Field("CustomerID").HeaderText("Customer ID").Width(70).Add();
                    col.Field("ShipCountry").HeaderText("Ship Country").Width(70).Add();
                .ClientSideEvents(e => e.ActionBegin("begin"))



namespace EntityCodeFirst.Controllers
    public class HomeController : Controller
        // GET: Home
        public ActionResult Index()
            List<EditableOrder> data = OrderRepository.GetAllRecords().ToList();
            ViewBag.datasource = OrderRepository.GetAllRecords().ToList();
            return View(data);



<ej:Grid ID="OrdersGrid" runat="server" AllowPaging="true">
           <DataManager Adaptor="remoteSaveAdaptor" UpdateURL="Default.aspx/Update" InsertURL="Default.aspx/Add" RemoveURL="Default.aspx/Delete" />
             <ClientSideEvents ActionBegin="begin" />
                 <ej:Column Field="OrderID" HeaderText="Order ID" IsPrimaryKey="true" Width="80"></ej:Column>
                 <ej:Column Field="EmployeeID" HeaderText="Employee ID" Width="80"></ej:Column>
                 <ej:Column Field="CustomerID" HeaderText="Customer ID" Width="70"></ej:Column>
                 <ej:Column Field="ShipCountry" HeaderText="Ship Country" Width="70"></ej:Column>
              <EditSettings AllowEditing="True" AllowAdding="True" AllowDeleting="True"></EditSettings>
              <ToolbarSettings ShowToolbar="True" ToolbarItems="add,edit,delete,update,cancel"></ToolbarSettings>



<ej-grid id="Grid" allow-paging="true" action-begin="begin">
<e-datamanager  json="(IEnumerable<object>)ViewBag.datasource" adaptor="remoteSaveAdaptor" insert-url="NormalInsert" update-url="NormalUpdate" remove-url="NormalDelete"></e-datamanager>
<e-edit-settings allow-adding="true" allow-editing="true" allow-deleting="true"></e-edit-settings>
<e-toolbar-settings show-toolbar="true" toolbar-items='@new List<string> {"add","edit","delete","update","cancel"}' /> 
        <e-column field="OrderID" header-text="Order ID" is-primary-key width="80" ></e-column>
        <e-column field="EmployeeID" header-text="Employee ID" width="80" ></e-column>
        <e-column field="CustomerID" header-text="Customer ID" width="70" ></e-column>
        <e-column field="ShipCountry" header-text="Ship Country" width="70" ></e-column>



<ej-grid [dataSource]="gridData" allowPaging="true" [toolbarSettings]="toolbarItems" [editSettings]="editSettings" (actionBegin)="actionbegin($event)" >
        <e-column field="OrderID" headerText="Order ID" [isPrimaryKey]="true" width="80"></e-column>
        <e-column field="EmployeeID" headerText="Employee ID" width="80"></e-column>
        <e-column field="CustomerID" headerText="Customer ID" width="70"></e-column>
        <e-column field="ShipCountry" headerText="Ship Country" width="70"></e-column>


TS File:

@ViewChild('grid') GridModel: EJComponents<any, any>;
export class GridComponent {
    public gridData: any;
    public editSettings;
    public toolbarItems;
    constructor() {
        this.gridData = ej.DataManager({ json: window.gridData;, updateUrl: "/Grid/Update", insertUrl: "/Grid/Insert", deleteUrl: "/Grid/Delete", adaptor: new ej.remoteSaveAdaptor() });
        this.editSettings = { allowEditing: true, allowAdding: true, allowDeleting: true};
          this.toolbarItems = { showToolbar : true, toolbarItems : ["add", "edit", "delete", "update", "cancel"]};
      if (args.requestType == "save" || args.requestType == "delete") {
               var value = "Value";
              args.model.query.addParams("val", value);



2. In actionBegin event we check the condition with the requestType and passing the value through addParams property of query API


<script type="text/javascript">
function begin(args) {
        if (args.requestType == "save" || args.requestType == "delete") {
            var value = "Value";
            args.model.query.addParams("val", value);




Value passed in ASP.NET Web Forms
