I am trying to set the default timezone (StartTimezone and EndTimezone) manually and was hoping to avoid pulling down another 3rd party library to do this.

"Automatic Timezone Detection Using JavaScript" http://pellepim.bitbucket.org/jstz/

 

Is there anyway to achieve this with window.kendo.timezone.zones  and getTimezoneOffset() ?

 

 

 

 

I'm trying to convert an existing TreeView that works with ajax/webapi, working with signalR and can't figure out how the requests for children are passed to the hub.

The datasource loads the root level fine by calling the read method without parameters, however the read method with the parent node ID parameter never gets called for child nodes.

I have set loadOnDemand to false and I can see multiple requests being made to the hub which appear to match the root nodes with children but get the following error:

signalR: treehub.read failed to execute. Error: There was an error invoking Hub method 'treehub.read'.

 

Has anyone got a working TreeView/signalr example or knw how to get lower level debug info.

 

Thanks

I have MVC application which has Kendo grid. The datasource's URL property is set to /Users/GetRequests . The application runs fine locally in visual studio. In production the application is hosted under virtual directory www.mycompany.com/dashboard 

So when we deploy application to production its not working with the url /Users/GetRequests, however if i change the url to /Dashboard/Users/GetRequests then it works but then it will not work locally. 

How can i set the relative URL to datasource?

Hello,

If I want to upload a large file in chunks, is there any suggestion? 

And, I had an upload control, and is there any method that I can fire "upload" in my code on demand.

      $("#files").kendoUpload({
        async: {
          saveurl: "Mary.aspx?save=1",
          removeurl: "Mary.aspx?remove=1",
          removeField: "removefiles[]",
          autoupload: false
        },
        multiple: true,
        showFileList: true
      }); 

 

Following is my kendo grid

@section scripts{
@Scripts.Render("~/bundles/jqueryval")
}

 @(Html.Kendo().Grid<Category>()
          .Name("grid")
          .Columns(columns =>
          {             columns.Bound(c => c.Id);    
              columns.Bound(c => c.Name)
                .ClientTemplate("<a href='" + Url.Action("Edit", "category") + "/#= Id #' " + ">#= Name #</a>").Width(140)
                .Filterable(ftb => ftb.Cell(cell => cell.ShowOperators(true)));

              columns.Bound(c => c.Color).Width(80).Filterable(false).Sortable(false).ClientTemplate("<div style='width: 25px; height: 25px; background: #=Color#;'></div>");

              columns.Bound(r => r.AltName).Width(240);

          
              columns.Command(command => { command.Edit(); }).Width(150);
          })
                   .Events(e => e.Edit("grid_edit"))
                .ToolBar(toolbar => toolbar.Create())
                .Editable(editable => editable.Mode(GridEditMode.InLine))
                .EnableCustomBinding(true)
                .HtmlAttributes(new { style = "height: 380px;" })
                .Filterable(ftb => ftb.Mode(GridFilterMode.Row))
                .Scrollable()
                .Sortable()
                .Pageable(pageable => pageable
                .Refresh(true)
                .PageSizes(true)
                .ButtonCount(5))
                .DataSource(dataSource => dataSource
                .Ajax().Read(read => read.Action("Get", "Person"))
                .Update(update => update.Action("SaveOrUpdate", "Person"))
                .Create(update => update.Action("SaveOrUpdate", "Person"))
               .Model(model =>
              {
                  model.Id(p => p.Id);
                  model.Field(p => p.Color).DefaultValue("#000000");
                  model.Field(p => p.Id).DefaultValue(new Guid());
                  model.Field(p => p.TenantId).DefaultValue(new Guid());
                  model.Field(p => p.RowVersion);
              })

                )
    )

Following is my viewmodel

public class Person
    {


        [Required]
        [Remote("IsPersonUnique", "Validation", "Admin" , AdditionalFields = "Id")]
        public string Name { get; set; }

        [UIHint("CategoryColorPicker")]
        public string Color { get; set; }

        public string AltName { get; set; }

    }

And my remote validation action method

public JsonResult IsPersonUnique(string name, Guid id)
        {
            return CategoryService.IsPersonUnique(name, id)
                ? Json(true, JsonRequestBehavior.AllowGet)
                : Json(false, JsonRequestBehavior.AllowGet);
        }

Now the remote validation doesn't fire when I am adding items inline in grid.
But it works fine when I add it through another detail page, for the same model.

But the required field validations work fine. 

 

In knockoutJS, I have become accustomed to "Flow Control" bindings for the HTML binding. Such as ...

foreach : http://knockoutjs.com/documentation/foreach-binding.html

and "with" : http://knockoutjs.com/documentation/with-binding.html

and if : http://knockoutjs.com/documentation/if-binding.html

and ifnot : http://knockoutjs.com/documentation/if-binding.html

These have become a vital part of the way I structure views and such, and I would be very upset to lose them. I notice that no such alternatives seem to exist in Kendo UI MVVM? Is this true? Are there any plans for such in the future? This is a very big deal breaker for me.

     I am building a web application which makes use of kendo UI  and angular-kendo.  The problem that I'm having is that the change event handlers, when specified in code, are never fired.

Example:


Whenever this is loaded at initial load of the application, the change event will fire.  If it gets loaded in a controller at a later time (think switching routes in ngRouter, or states in angular-ui-router), the change event will not get fired.

If I specify the k-on-change directive, like this:
the specified change handler will fire, no matter when the HTML gets loaded.

The problem isn't just with the datasource.change event either.  The kendoPager.chancge event didn't work either when in code.

What does angular-kendo do differently at initial page load than at a partial view load that would cause that problem?  Is there a way to work around it? (Aside from specifying k-on-change)

Hello Telerik Folks,

 We are trying to do custom filtering on the Client leveraging the Kendo Grid dataSource.Filter() functionality in JavaScript.  We have created a header above our grid that allows a user to select many filter criteria and then we apply them for the user all at once in a JavaScript function.  This approach has many benefits for us in that it allows us to create a cleaner more intuitive interface up top that shows all of the Users' filtering selections together.  It also allows us to leverage Kendo Grid's paging without having to write our own paging and filtering Server side.

The local ApplyFilter() function that pieces together the JSON needed to create the combined multi-column filter into a newTotalFilter string.  We then apply this filter at the end with this logic.

 

This works great, but we are running into problems when constructing filters that appear to push the limits of what this type of Filtering can do.  Fox example for some columns we provide a checkbox list to allow users to select the items they want to appear below.  This is comparable to a SQL 'IN' statement.  As the Kendo Grid doesn't have an 'IN' filtering functionality we try to piece together several 'Contains' with an 'Or' for that particular column.

So for example, there might be a checkbox list with 

• ItemA
• ItemB
• ItemC
• ItemD
• ItemE

 The user might select or Check Items A,B & C.  We would then build out the ​JSON to look like this...

 But when we apply the above JSON we only get the first two rules applied to the ItemsColumn.  We can see the limitation if we go into the UI for the column filter.  It only shows the first two being applied.  (Please see attached image.)

 So what we are wondering is, is there a way to increase or get around this apparent 2 rule limit to the number of filter rules that may be applied to a single column?   ...We would like to construct and apply filters in JSON and not be limited to two rules per column.  

 

 

 

I want to change the format from to include seconds.

If the timepicker receives any format it thinks is invalid, it defaults back to "hh:mm tt", hiding the error

I couldn't find any documentation on whether it support seconds at all, or what an actual valid format string looks like.

I've tried "HH:mm:ss" among a few other things but this does not work.

I was trying to develop a complex view that is composed by the following structure:

I have a MainGrid that is editable by a custom popup template. Inside this custom popup template I'm trying to render another Grid (SubGrid) and my problem is because one field (column) of this SubGrid is DateTime. When the browser try to render this bundle it raises a JS exception ILLEGAL TOKEN, but when I remove the DateTime field of the SubGrid the browser can render normally the both grid (MainGrid with custom template and SubGrid).

Do you know if there are any issue about DateTime field on grid inside custom template editor for another grid?

How could I solve this issue ?

 Thanks
