Hi,

 

I discovered a problem with ClearPromptChar configuration. When I set ClearPromptChar to true, I expect that the mask signs should not be in the output. I.e. when I define mask 000-000 and insert 123-456 into the MaskedTextBoxFor the output should be 123456. I would like to avoid removing "-" manually.

Example available at: http://dojo.telerik.com/aTEROJIG/3

Should it work as I expected or I misunderstood?

 

Thanks,

   Tomas.

Excellent Widget! Really appriciated, but somehow I can't seem to get the headertemplate working. I don't see it appear in the dropdown header. While i inspect the DOM with chrome  dev tools the 'HEADER' phrase is not found. It look's like this method does nothing. or am i mistaken?  And it would also be nice if the widget would have lambda selectors for allmost all property's. Most widget have these selectors, only using string selectors make it error prone (model change is not reflected in this string selector)

@(Html.Kendo().MultiColumnComboBoxFor(m => m)
    .DataTextField("Afkorting")
    .DataValueField("idPersoneel")
    .Filter("contains")
    .FilterFields(new string[] { "Afkorting", "OpgemaakteNaam", "Team" })
    .Columns(columns =>
    {
        columns.Add().Field("Afkorting").Title("Afkorting").Width("50px");
        columns.Add().Field("OpgemaakteNaam").Title("Naam").Width("120px");
        columns.Add().Field("Team").Width("60");
        columns.Add().Field("Omvang").Width("50");
        columns.Add().Field("Resturen").Width("50");
    })
    .HeaderTemplate("HEADER")
    .FooterTemplate("Total \\#: instance.dataSource.total() \\# items found")
    .HtmlAttributes(new { style = "width:100%;" })
    .Height(500)
    .DataSource(ds =>
        {
            ds.Read(read => read.Action("Personeelsleden", "Personeel", new { Area = "Tabellen" }).Data("passPersoneel"));
            ds.Events(e => e.Error("DataSourceRequestErrorHandler"));
        }
    )
    .ToClientTemplate()
)

I've got a grid, with a pop-up edit form, where there is some controller level validation applied before the record is saved.

The grid is defined:-
The error handler is:-

This works fine, displaying the error message if the validation fails. However, I have two problems:-

1. After displaying the alert, the edit form is closed, so the user can't correct their error - they have to start all over again
2. Even though the record hasn't been saved - a new record is displayed in the grid, and only after refreshing the grid does it disappear.

How can I solve these two issues?

Thanks

Hi, in a grid popup edit template I got a field bound like:

@Html.HiddenFor(model => model.LogoUrl)

This field represents an image URL stored in Azure Blob.

I already got a Kendo Upload in the edit template that upload the image to Azure, but in the KendoUpload success return function, I need to set the URL received by azure in the object currently edited. For now I try this:

 

But the databinding are not hit and the underlying model is not changed. How I can achieve that?

Hi,

I have issue with chart after upgrade kendo libraries to R3 2018 (ver. 2018.3.911.545). Here is my code snippet:

 

and this is my layout with references:

 

I also already updated it with telerik.ui.for.aspnetmvc.hotfix.2018.3.911.commercial libraries but still getting the same error. Fyi my project use MVC 5 and bootstrap 4.

Any thoughts on how to fix this greatly appreciated.

Thanks.

 

We have a Web API where the controller classes implements ApiController. 

The CRUD-operations looks like:

public IHttpActionResult Get()
public IHttpActionResult Get(int id)
public int Post(Company company)
public void Put(Company company)
public void Delete(int id)

Adding a Kendo UI ASP.NET MVC Grid that view data works, but we got stuck binding to datasource when we tried to implement inline-editable rows. 

The API methods on the demo page, https://demos.telerik.com/aspnet-mvc/grid, takes a DataSourceRequest as a parameter. 
Here it gets confusing especially when the documentation is not so comprehensive.

Can't we just use our API as it is, do we need to create yet another class where all the CRUD-operations takes the DataSourceRequest parameter?

 

if I add:

.Group(g => {
                g.Add(c => c.DistrictName);
                g.Add(c => c.SchoolName);
                })

to my datasource:

.DataSource(ds => ds
            .Ajax()
            .ServerOperation(false)
            .Read(read => read.Action("RetrieveReqStatusReport", "ReportSupport", new { orgId = ViewBag.OrgSelection.Id, personId = ViewBag.PersonId, yearId = ViewBag.YearSelection.Id }))
            .PageSize(50)
            .Group(g => {
                g.Add(c => c.DistrictName);
                g.Add(c => c.SchoolName);
                })
        )

then

 function filterMenuInit(e) {
        if (e.field == "DueDate") return;
        var filterMultiCheck = this.thead.find("[data-field=" + e.field + "]").data("kendoFilterMultiCheck")
        filterMultiCheck.container.empty();
        filterMultiCheck.checkSource.sort({ field: e.field, dir: "asc" });

        filterMultiCheck.checkSource.data(filterMultiCheck.checkSource.view().toJSON());
        filterMultiCheck.createCheckBoxes();
    }

generates the following error when I try to filter:

Uncaught ReferenceError: DistrictName is not defined
    at eval (eval at compile (kendo.all.min.js:25), <anonymous>:3:209)
    at Object.render (kendo.all.min.js:25)
    at Object.d [as render] (jquery.min.js:2)
    at init.createCheckBoxes (kendo.all.min.js:45)
    at init.filterMenuInit (1:371)
    at init.trigger (kendo.all.min.js:25)
    at init.c (kendo.all.min.js:53)
    at init.trigger (kendo.all.min.js:25)
    at init._init (kendo.all.min.js:45)
    at init._click (kendo.all.min.js:45)

if I remove it, multi-filter works fine.

TIA for the insight into what I'm failing to understand.

Hi,

I need to filter a combobox based on the value of a check box.
I explain.

I have a checkbox that will start unchecked (value 0).
And below is a combobox that will use an api to fetch the data.
If the user selects this checkbox, the data from the combobox must be updated.

Very similar to this example: https://demos.telerik.com/aspnet-core/combobox/cascadingcombobox
But using the checkbox.

Can someone help me?
I am using ASP.NET MVC Core.

 

http://demos.telerik.com/kendo-ui/grid/aggregates

here i see an example for grid grouping. Now I want to sort the groups by the aggregate count.  I search the help document and only find sorting settings like "dir: 'desc'", which can only sort groups by field value, not the count of group elements. 

Can someone tell me how to set the configuration to make grid groups sorted by element count?

I have an old application where the user was entering an input a dropdown list (of multiple values concatenated) was displayed and he could filter the list based on the values displayed.

Now we decided to use Combobox since the Autocomplete does not open the dropdown when the autocomplete receives focus. Since the list contains too many values I though I should try also virtualization

However when I write something in the combobox no event is triggered on the server. If I open the dropdown manually the server is called.

I tried removing the Virtual and the result was the same (Probably it did not worked because I left the Ajax and the PageSize).
