How to get querystring value to Kendo Grid update method and pass to MVC controller

[Ron]

Hi, I have a kendo grid and need to get a querystring value.  See below code.

 

Browser Url = http://blahblah/blah/36?EvaluationCriteriaGrid-mode=edit&chiefEvalCriteriaId=110

 

UI.cshtml

                                

@(Html.Kendo().Grid(Model.ChiefEvaluationCriteriaList.AsEnumerable())
                        .Name("EvaluationCriteriaGrid")
                        .Columns(columns =>
                        {

                            columns.Bound(p => p.EvaluationCriteriaName);
                            columns.Bound(p => p.MinScore).Width(100).Title("Min Score").Format("{0:0}");
                            columns.Bound(p => p.MaxScoreDisplay).Width(100).Title("Max Score");
                            columns.Command(command => { command.Edit(); }).Width(180).Title("Action");
                        })
                        .CellAction(cell =>
                        {
                            if (cell.Column.Title == "Action")
                            {
                                if (cell.DataItem.EvaluationResultID ==
                                    ServiceProxy.Model.DomainConstants.EVALUATION_RESULT_APPROVED)
                                {
                                    cell.HtmlAttributes["style"] = "display:none;";
                                }
                            }
                        })
                        .Editable(editing => editing.Mode(GridEditMode.InLine))
                        .Pageable()
                        .Sortable()
                        .Scrollable()
                        .DataSource(dataSource => dataSource
                        .Server()
                        .Model(model => model.Id(c => c.ChiefEvaluationCriteriaID))
                        .Read("EvaluationQuestionnaire", "EvaluationCriteria", new { area = "Proposal", Id = Model.SolicitationDetails.SolicitationID })
                        .Update("EditEvaluationCriteria", "EvaluationCriteria", new { area = "Proposal", Id = Model.SolicitationDetails.SolicitationID })

                    )

                )

 

Controller.cs

[HttpPost]

 public ActionResult EditEvaluationCriteria( int Id, int chiefEvalCriteriaId, int maxScoreDisplay, int minScoreDisplay = 0 )
        {

               if (ModelState.IsValid)
                    {
                       Do something
                     }

 

                    return view

        }

 

 

Thank you for the support

Hello Ron,

Thank you for the code snippets and details provided.

Could you please confirm in which Event handler the query string should be sent to an Action Method of the Controller:

• https://docs.telerik.com/kendo-ui/api/javascript/ui/grid#events

For this case, here is the approach that I could recommend:

1. Handle the proper Event of the Kendo UI Grid.
2. In the Event handler, get the querystring.
3. Build and execute an Ajax request for sending the querystring to an Action Method in the Controller.
4. Receive the querystring.
5. *For this case, I would recommend dividing the string into parts in the Controller. In another way, you will need a couple of Ajax requests.

I hope this information helps.

 

Kind Regards,
Anton Mironov
