Hi, my KendoUI version is v2015.2.902, i use a kendo grid for server paging, sorting, filtering and now i would like to add grouping functionality.
I use "function read" mode for dataSource calling asp.net mvc controller method. (server side request object is a Kendo.Mvc.UI.DataSourceRequest object)
this is my dataSource configuration:

let dataSource: any = {
  batch: true,
  serverPaging: true,
  serverSorting: true,
  serverFiltering: true,
  serverGrouping: true,
  page: 1,
  pageSize: 20,
  transport:
  {
      read: function (options)
      {
          kendo.data.transports["aspnetmvc-ajax"].fn.options.options = { prefix: '' };
          let request = kendo.data.transports["aspnetmvc-ajax"].fn.options.parameterMap(options.data, "read", false);

          thisObject.httpService.GetNodes(request)
          .then(function (args: IHttpServiceParameters)
          {
              options.success(args.data);
          });
      }
  },
  schema:
  {
      data: function (data)
      {
          return data.Data;
      },
      total: function (data)
      {
          return data.Total;
      },
      groups: function (data)
      {
          return data.Data;
      },
      model: model
  }
};

if i not use grouping all work fine, but using grouping the data result object seem not binding correctly.

args.data.Data returned from server has this schema:

[{ AggregateFunctionsProjection: null, 
   Aggregates: {}, 
   HasSubGroups: false, 
   Items: [],      <--- Keep note of this element name
   Key: "Invoice", 
   Member: "InvoiceColumnName", 
   Subgroups: [], 
   value: undefined 
 }, 
...]

the problem is when kendo.all.js parse the response of the server, passed from args.data.Data to convertGroup function (kendo.all.js line 7049)
in this function there is a call who reference to record.items object but the object in data returned from server is called Items (starting with uppercase)

kendo.all.js code:
function convertGroup(data, getters, modelInstance, originalFieldNames, fieldNames) {
      var record,
          idx,
          fieldName,
          length;

      for (idx = 0, length = data.length; idx < length; idx++) {
          record = data[idx];

          fieldName = originalFieldNames[record.field];
          if (fieldName && fieldName != record.field) {
              record.field = fieldName;
          }

          record.value = modelInstance._parse(record.field, record.value);

          if (record.hasSubgroups) {
              convertGroup(record.items, getters, modelInstance, originalFieldNames, fieldNames);    <--- Here the problem !!
          } else {
              convertRecords(record.items, getters, modelInstance, originalFieldNames, fieldNames);  <--- Here the problem !!
          }
      }
  }

do you have any suggestion? why the object returned from server have Items property insted of items?
How to solve?

Hi Everyone, 

 I have a question regarding the ASP.NET MVC Dropdownlist.

 I load my DDL with data from the controller like this. 

this result return a list of countries and add them to the DDL. 

Everything is fine, but how can I set the selectedIndex by the text and not the ID in the list?

I can't be sure that Denmark is always number 185. 
​

 If I have a treeview with .DataSource(d=>d.Model(....).Read(r=>r.Action(....)))

Can I use .ItemAction() to set item.checked based on a field provided in the DataSource?  How?

In the code below, what would I put in place of the bolded comment?

@( Html.Kendo()
       .TreeView()
       .DataTextField("Name")
       .Name("userPermissionsTree")

       .Checkboxes(cbxConfig => cbxConfig.Enabled(true)
                                         .CheckChildren(true)
                                         .Name("checkedNodes"))
       .DataSource(d => d.Model(m =>
                                {
                                    m.Field("enabled");
                                    m.Id("permissionId")
                                })
       .Read(read => read.Action("PermissionsTree_Read",
                                                   "SettingsUsers",
                                                   new {
                                                       userId = Model
                                                   })))
      .ItemAction(item=>item.Checked=    /*******set to true if field enabled is true**********/    )
      .Events(events => events
        .Check("onPrivilegeCheck"))
      )

How can I make editable first 3 columns of telerik grid? I can make editable the whole row but I need only first 3 columns.

 

 

Thanks.

 For some unknown reason I can't seem to get my EditTemplates to work if I have them in a folder named "EditorTemplates" in the same folder as my view containing the Kendo UI Grid (MVC) but if I put the same file in Shared/EditorTemplates it works. If I look at this example the Edit Template is setup as indicated above but is working (I guess). 

https://github.com/telerik/ui-for-aspnet-mvc-examples/tree/master/grid/custom-popup-editor/KendoUIMVC5/Views/Home

 

What do I need to do to get it to work from an EditorTemplates folder in same folder as my main view?

I have a window (apologies for bolding... seems easiest way to distinguish code given limited formatting options)

     @(Html.Kendo()
          .Window()
          .Name("UserPermissionsWindow")
          .Title("User Privileges")
          .Content("loading privlege settings...")
          .Iframe(true)
          .Draggable()
          .Resizable()
          .Visible(false))

 

opened by a button click from a grid row:

          columns.Command(com => com.Custom("Privileges")
                                    .Click("openUserPermissionsWindow"));​

 The click handler calls the window refresh button:

 <script type="text/javascript">
    function openUserPermissionsWindow(e) {
        e.preventDefault();
        // the dataitem retrieved here will have the field values that can subsitute in the template (I hope)
        var dataItem = this.dataItem($(e.currentTarget).closest("tr"));
        personId = dataItem.Person_ID; //will this work?????
        var wnd = $("#UserPermissionsWindow").data("kendoWindow");
        wnd.refresh({
            url: "UserPrivileges/" + personId, // what does this url need to look like?
            data: { id: personId }
        });
        wnd.center().open();
    }
</script>

And the action returns a partialview containing a treeview wrapper:

 
<b>yo 'sup?</b>
@( Html.Kendo()
       .TreeView()
       .DataTextField("Name")
       .Name("userModulePermissions")
       .Checkboxes(cbxConfig => cbxConfig.Enabled(true)
                                         .CheckChildren(true)
                                         .Name("checkedNodes"))
       .DataSource(d => d.Read(read => read.Action("PermissionsTree_Read",
                                                   "SettingsUsers",
                                                   new {
                                                           userId = Model
                                                       })))
      )

But I end up with javascript error:  ReferenceError: jQuery is not defined

This is "fixed" by putting the jquery (and kendo?) bundles at the top of the PARTIAL view:

 @Scripts.Render("~/bundles/jquery")

@Scripts.Render("~/bundles/kendo")​

But because this is a PartialView in a window on a page that already exists, shouldn't it be able to use the jquery library that is already on the page?

I don't think I should have to bundle jquery libraries on partial views.

Currently the jquery bundle is at top of layout page.

Please advise.

 

We are experiencing an issue with the Kendo ui datetime picker in our MVC Sitefinity application. The issue manifests itself only in IE after a workaround JavaScript function has been applied. The application's default culture is set to fr-CA however in the view the date format needs to be fr-FR. If submit is clicked and the text area of the datetime picker is empty the validation message as set on the model property is displayed correctly, however if any non valid text is entered into the text area then the validation message displayed is: "DateDebut is not a valid date". The workaround function replaces the data-val-date attribute displaying the correct validation message in the French language and as stated works in all browsers but IE.  As show below the kendo culture is set to fr-FR.​

 

 

 

I am trying to use a JQuery command to call the ​Create action on a grid.  Reason for this is that i need to pass an external id to the create command that is currently stored in a hidden HTML input field.

Here is the code

        //$("#Child").data("kendoGrid").dataSource.read({ accountId: accId });​

The alert in the script is telling me that acctid is populated... i just want to call the create action.... the error i am getting is that dataSource.create is not a function

 

Thanks for any help on this issue.

Hello

I have a scheduler with a custom edittemplate that sets the usual stuff like title, start, end and so on.
Furthermore my template contains a javascriptfunction for adding or subtracting workers from the event and storing the result in an array called taskOperators.

How do I pass that array to my controller action for create and update?

I saw something about adding .Data method to the .Update and .Create but how do I bind that to my Array taskOperators?

Best regards

Jonas

I occasionally see 404 Not Founds in our logs on the DejaVu fonts. I see they were added in Q3 2014 for PDFs but I am not using PDF exports. I do not have the fonts in the css/fonts folder since I did not think I needed them. The page does have a grid control.

 Any idea on why these are being requested? I can't reproduce this so can't see the source to debug it. Of course one solution is to add the fonts to the project.

 Thanks
