I have very large data sets I want to display in a grid, and I'd like to use the auto filtering on the column header.  But with my large data sets, users will typically want to specify a few filters before getting their data, otherwise the retrieval of the records from the database takes a very long time.

It seems that by default, each filter in the grid is applied immediately.  I'd like to allow the user to select multiple filters, and then push a button to trigger the refresh.

Is there a good way to skip the automatic refresh that comes with setting a filter in the grid header?

Hi

I have installed a trial version to have a play around with the Scheduler control.

I have put together a basic ​page, but have a problem when attempting to edit an event.  After double clicking on the event, the event dialog opens. Then, whenever I hit Cancel or the close (X) button, I get the following error:

 Unhandled exception at line 10, column 30735 in kendo.all.min.js

Javascript runtime error: unable to get property 'uid' of undefined or null reference.

The Save button works fine. 

 I am using Kendo.Mvc.dll 2015.2.805.545, and Visual Studio 2013.

 Any ideas on why this is failing?

Cheers, Jarrod

Hi

 Please may we have a similar "Navigator" feature as in the Stock chart, for the Scatter chart.

 At least where the X axis is time.

 This would be of great benefit.

 Alternatively how may we customise using two sliders a similar feature.

 Kind Regards

Hello,

 I have been trying to figure out how to set value of my multiSelect after server filtering and adding some conditions so that some elements cannot be deleted.  The multiselect works fine *as long* as the user uses the mouse to select elements to add. Once the user decides to filter by using the keyboard the multiselect does not render the added item correctly even though the values i set to them are correct.Here is my code:

Edit.cshtml:

   @Html.Kendo().MultiSelect().Name("msGroupMembers").DataTextField("FullName").DataValueField("Id").Value(new[] { new { FullName = Model.SelectedTO.Select(x => x.Text), Id = Model.SelectedTO.Select(x => x.Value) } }).Filter(FilterType.Contains).Events(e => e.Change("onChangeEdit").Close("onCloseEdit").Select("onSelect")).DataSource(source => source
                        .Custom()
                        .Transport(transport => transport
                        .Read(read =>
                        {
                            read.Action("GetGroupMembers", "ScheduleRequest")
                            .Data("testOfficerFiltering");
                        }))
                        .ServerFiltering(true)).HtmlAttributes(new { required = "required" })

 Controller:

  public ActionResult SetGroupMembers(List<int> items, string teamLead)
        {
            Business.Entities.RTSSUser user = userService.GetRTSSUser(User.Identity.Name);

            // check to see if we have a lead.
            int lead;
            bool result = int.TryParse(teamLead, out lead);
            if (!result)
            {
                lead = -1;
            }

            try
            {
                int findLead = items.FindIndex(s => s == lead);
                int findOwner = items.FindIndex(s => s == user.Person.Id);

                //if our owner is also the lead, place in first spot
                if (findLead == findOwner && findOwner == -1)
                {
                    items.Insert(0, user.Person.Id);
                }

                else if (findLead == -1)
                {
                    items.Insert(1, lead);
                }

                else if (findOwner == -1)
                {
                    items.Insert(0, user.Person.Id);
                }

            }
            catch (Exception e)
            {
                // handle an empty list passed.
                List<int> msUsers = new List<int>();
                msUsers.Insert(0, user.Person.Id);
                return Json(msUsers, JsonRequestBehavior.AllowGet);
            }
           
            
            return Json(items, JsonRequestBehavior.AllowGet);
        }​

Javascript:
function onChangeEdit(e) {
   
    var lead = $("#cbTeamLeadName").data("kendoComboBox").value();

    var msValue = this.value();
    var arrayLength = msValue.length;
    var newArrayValue = new Array();

    //store values into array
    for (var i = 0; i < arrayLength; i++) {
        newArrayValue.push(msValue[i]);
        console.log(msValue[i]);
    }    

    //get owner
    $.ajax({
        type: 'GET',
        url: SetGroupMembersUrl,
        data: {
            "items": newArrayValue,
            "teamLead": lead
        },
        contentType: 'application/json',
        async: true,
        cache: false,
        dataType: 'json',
        traditional: true,
        success: function (data) {          
            populateMs(data);
         
        },        
        error: function () {
            console.log("Could not get AgencyName");
        }
    });
    
}

 
function populateMs(e) {
    var multiSelect = $("#msGroupMembers").data("kendoMultiSelect");
    multiSelect.dataSource.filter({});
    multiSelect.value([])
    multiSelect.refresh();
    multiSelect.value(e);
    alert("Dat: " + e);
}

I have found this similar thread: http://stackoverflow.com/questions/22010796/kendo-multiselect-value-setting-bug and was wondering if it is a bug or if i am doing something wrong. Thanks in advance!

I have been looking at the datepicker mask example at

http://docs.telerik.com/kendo-ui/aspnet-mvc/helpers/datepicker/how-to/masked-date-picker-grid

Is this solution valid for MVC wrappers also?

I have included the code but still no mask.

Thanks

I have a simple grid w/ ajax binding and some nested grids, all i want to do is have an inline edit for one field and set the other 2 to readonly.  One of the fields is a bool and when i set Editable(false) in the datasource model i get an exception saying that the value passed to the dictionary is null but with Editable(true) or no Editable call it works fine.  The RequireAll bool shouldnt be changeable in this grid, its just there for reference.  

Maybe i'm just doing something wrong, i just started using these controls.  

As a side note i've noticed that sometimes the RequireAll column renders as 'true'  or 'false' and sometimes with a green icon that says Yes.  is it possible to force the icon style to display when readonly instead of the true false?

Hello,

 If the Telerik controls do not support this, then I would like to know. Thanks in advance

 I have a Grid that binds to a ViewModel, that in turn has 2 other types of classes as its properties. I am trying to populate the grid rows with both, and either property could be Null. In one of these classes, there is a property that is a List<Skill> where each of the Skills are classes that has a string that I need to concatenate into a larger one to display for the 'Skill' grid column. Right now I'm just making the concatenated string in the controller and adding an extra property onto my ViewModal:

 columns.Bound(p => p.SkillsDisplayed).Title("Skill").ClientTemplate("<p>#= SkillsDisplayed ? SkillsDisplayed : '' #</p>");

 My question is: is there a way to put a Razor block in the ClientTemplate (or some other way in the column binding) to iterate through the List<Skill> and concatenate those object's strings together and display the resulting string? I have already tried this with javascript similar to the above, but the nested '#'s' makes such a function highly unreadable and I'm not sure I can achieve that anyways. Is this even possible?
