Hi,

We have recently changed some legacy code which was calling a WCF API to populate the grid and it was using serverside paging. We have to use the same serverside paging but with C# datasource. How can we achieve this?

This is how the code was before when it used an API:
dataSource: {
    type: "odata",
    transport: {
        read: dataUrl,
        dataType: "json"
    },
    schema: {
        model: BillingModel,
        data: function (data) {
            return data["value"];
        },
        total: function (data) { return data['odata.count']; }
    },
    serverPaging: true,
    serverFiltering: true,
    serverSorting: true,
    sort: { field: "EncounterDate", dir: "asc" }
}

This was changed to use the c# datasource now:

dataSource: {
    schema: {
        model: BillingModel,
    }
}

Hello Forum:

I have a Kendo UI button in a header of a layout, and I would like to hide it using jQuery:

$("#option-button").css('display', 'none');

But the button doesnt hide, is there any way to hide it using a specific function in Kendo UI?

I will appreciate any help.

Thanks!

I am having hard time implementing server side pagination using Kendo UI Grid. I have a POST route `/worklist` that does return results when I supply params to it but I am unable to use it using the Kendo UI grid, I have searched a lot online but I cant find anything useful. Here is the result that is returned by the URL when I use Postman to supply params to it. 

    {"header":{"cursor":{"pageable":{"sort":null,"offset":0,"pageSize":5,"pageNumber":0},"page":0,"size":5,"numberOfElements":5,"totalElements":26315,"totalPages":5263},"filter":{"dobFrom":null,"dobTo":null,"inFacility":null,"inICURoom":null,"isICUBaby":null,"hasDocumentWaitingApproval":null,"hasNotification":null,"statusInfoCompleted":false,"statusToBeScreened":false,"statusConsentRequired":false,"statusSecondScreeningDateRequired":false,"statusSecondScreeningDateGiven":false,"statusAppointmentDateRequired":false,"statusAppointmentDateGiven":false,"statusReferredToENT":false,"statusFirstHourOfRehabGiven":false,"statusHaRecommended":false,"riskFactorCode":null,"facilityFollowingPatient":true,"readyToBeScreened":false,"restrictToMyPatientList":false}},"rows":[{"patientId":43101,"patientName":"LAUZON, FLORENCE","sex":"F","statusIcon":"KARAN_ICON","birthDate":"2014-07-22","decesedDate":null,"ramq":"LAUF14572215","mrn":"3009796","mrnFacilityCode":"CHUSJ","followUpFacilityCode":"CHUSJ","location":null,"age":"6 ans 4 mois","motherMaidenName":null,"phoneNumber":"(514)260-8227","address":"1425 RUE UNION","city":"SAINTE-CATHERINE","postalCode":"J5C 1G8","status":"Réussite - fin du PQDSN","statusDate":"2014-08-12"},{"patientId":43102,"patientName":"BETOURNAY, KEITH","sex":"M","statusIcon":"KARAN_ICON","birthDate":"2014-08-18","decesedDate":null,"ramq":"BETK14081812","mrn":"3010677","mrnFacilityCode":"CHUSJ","followUpFacilityCode":"CHUSJ","location":null,"age":"6 ans 3 mois","motherMaidenName":null,"phoneNumber":"(514)451-7657","address":"1735 RANG DUMAS","city":"ORMSTOWN","postalCode":"J0S 1K0","status":"Réussite - fin du PQDSN","statusDate":"2014-08-24"},{"patientId":43103,"patientName":"BETOURNAY, MARLY","sex":"F","statusIcon":"KARAN_ICON","birthDate":"2014-08-18","decesedDate":null,"ramq":"BETM14581814","mrn":"3010678","mrnFacilityCode":"CHUSJ","followUpFacilityCode":"CHUSJ","location":null,"age":"6 ans 3 mois","motherMaidenName":null,"phoneNumber":"(514)451-7657","address":"1735 RANG DUMAS","city":"ORMSTOWN","postalCode":"J0S 1K0","status":"Réussite – surveillance en audiologie recommandée","statusDate":"2014-09-04"},{"patientId":43104,"patientName":"CLIMACO-DOS SANTOS, MATHEO","sex":"M","statusIcon":"KARAN_ICON","birthDate":"2014-07-21","decesedDate":"2015-03-24","ramq":"CLIM14072117","mrn":"3011417","mrnFacilityCode":"CHUSJ","followUpFacilityCode":"CHUSJ","location":null,"age":"6 ans 4 mois","motherMaidenName":null,"phoneNumber":"(438)403-2806","address":"1448, RUE TARDIVEL","city":"LAVAL","postalCode":"H7K 0C2","status":"Décédé","statusDate":"2015-03-24"},{"patientId":43105,"patientName":"CHAGNON, BB DE SINDY","sex":"F","statusIcon":"KARAN_ICON","birthDate":"2014-08-04","decesedDate":null,"ramq":null,"mrn":"3011180","mrnFacilityCode":"CHUSJ","followUpFacilityCode":"CHUSJ","location":null,"age":"6 ans 4 mois","motherMaidenName":null,"phoneNumber":"(450)793-2578","address":"72 DION","city":"SAINT-LIBOIRE","postalCode":"J0H 1R0","status":"Réussite – surveillance en audiologie recommandée","statusDate":"2014-09-04"}]}
This is the result when explicitly mention that I need the first five results , how can I display this through kendo UI Grid, I am using the `pageSize` and the `total` records variable but no luck. 
Here is my jQuery Kendo UI code

    $('#grid').kendoGrid({
            dataSource: {
                transport: {
                    read: function (options) {
                       $.ajax({
                           type: "POST",
                           contentType: "application/json",
                           url: "worklist",
                           dataType: 'json',
                           cache: false
                       })
                    }
                },
                serverPaging: true,
                timeout: 600000,
                pageSize: 10,
            },
            schema: {
                total: '26315',
                model: {
                    fields: {
                        patientName: { type: 'string'},
                        birthDate: { type: 'string'},
                        phoneNumber: { type: 'string'},
                        ramq: { type: 'string'},
                        address: { type: 'string'},
                        mrn: { type: 'string'}
                    }
                }
            },
            height: 550,
            filterable: true,
            sortable: true,
            pageable: true,
            columns: [
                {
                    field: "patientName",
                    title: 'Patient name'
                },
                {
                    field: "birthDate",
                    title: 'BirthDate'
                },
                {
                    field:"ramq",
                    title:"RAMQ"
                },
                {
                    field:"address",
                    title: "Address"
                },
                {
                    field:"mrn",
                    title: "MRN"
                }]
        });

    });

using this, in my network tab I keep getting a 404 Not found, apparently the library is not supplying any params to the request, however I do see the empty Kendo UI grid being displayed on the page.Thanks for the help

I am using the following JSON data in my Kendo ListView DataSource:

 

Now here is my goal/issue. I would like to filter the datasource when a checkbox is checked and the field I would like to filter by is the `ProductTypes.Name` field.

However, I'm not sure how to get this working correctly.

Here is my DataSource:

 

And here is how I'm currently trying to filter but it's not working:

 

If I check the checkbox that has the name "Cage Free" for example, all of the items in the listview are hidden.

I have a grid that has a few column templates defined.  Some are using data-bind="click: clickHandler" and some have custom and kendo widgets within them.  When I use a DataSource making a remote data call, it seems like the kendo.bind() is not being applied to the rows in the column.

JS Fiddle example here which has an "Action" column with a simple data-bind click handler that will not fire:
http://jsfiddle.net/jeastburn/VgtDM/

I found I can call kendo.bind() on the dataBound Grid event, but this feels like a hack and I lose the ability to have data-bind events pass the row data rather than my top-level Observable object I use in the bind() call..

I'm totally new to Telerik and the example that I want to build upon is defined in this style:

        <kendo-grid name="grid" height="550">
            <columns>
                <column field="Facility_Id" title="Facility"/>
                <column field="Name" title="Name"/>

when I look for hints on what is possible, I find only this style:

        $(document).ready(function () {
            var grid = $("#grid").kendoGrid({
                columns: [
                    { field: "FirstName", title: "First Name", width: "140px" },
                    { field: "LastName", title: "Last Name", width: "140px" },
                    { field: "Title" },
                    { command: { text: "View Details", click: showDetails }, title: " ", width: "180px" }]
            }).data("kendoGrid");

 

Which is the preferred one and where do I find examples for the first style please?

Thanks

I have the following:

@(Html.Kendo().ListView<CourseServiceModel.CourseSearchResult>(Model)
       .Name("CourseListView")
       .TagName("div")
       .ClientTemplateId("template")
       .DataSource(dataSource =>
       {
       dataSource.Read(read => read.Action("GetSearchedCourses", "SearchCourse").Data("getSortBy"));
       dataSource.PageSize(10);
   })
       .Pageable(x => x.PageSizes(true).Refresh(true).Info(true).PageSizes(new int[]{10,25,50}))
     )

On the first time the page loads, the datasource is read as expected. On subsequent post the datasource does not get read, no ajax calls.

Works fine in FF and Chrome only an issue in IE (8,9).

Sounds like a caching issue but not sure where to start....

The page navigation is <page to set search criteria> -> RedirectToRoute("Results") -> <Results (contains ListView)> 

I have been doing a static code analysis of my entire project with the KIUWAN tool

This tool has found some security issues in some Kendo JS files

I would like to know if they are false positives or if it can be justified in some way that there are no security problems

Problems found (the most important are the first 3):

• Do not update control vars in 'for' loop body Maintainability Control flow
• Potential denial-of-service attack through malicious regular expression(ReDoS)
• Never use JavaScript 'history' object or navigation-based positioning
• Avoid unused local variable 
• Avoid accessing unreliable variable properties 
• Standard pseudo-random number generators cannot withstand cryptographic attacks
  
  The details of the analysis are in the attached file (a zip with a pdf file)

Kendo version: 2020.2.513

 

Hi, we need to use the setOptions function when we resize the window, to set the new gantt height.

We also use the "resizable" property.

The problem is, after a "column resize", the inner "option" column width is not set to the object.

So, when we use setOptions, the columns size are back to original.

We found a workaround, where we edit the inner option column size property after a "colunnResize" event, but I think that it's a bug and it should be done by the component itself automatically.

https://dojo.telerik.com/@foxontherock/uCulUjiy/6

I also tried to keep the "listWidth" by binding the "resize" event of the inner splitbar, but I think it's not a kendo splitter, but a custom spliter made just for the gantt, and it doesn't work.

We’re using the Kendo Grid and need to  make it  ADA compliant . We're using a tool called JAWS for verifying the ADA compliance.
Below are some of the issues we noticed:

1) How can we set focus on the Edit popup screen from kendo grid?

2) Say once the focus is set on Edit popup form ;How can we navigate to the other controls on the popup screen ?

3) How can we exit out of the edit popup screen and set focus back to the main grid ?  

 

Thanks,
