Hi,

A seconde question about the DataSource is how can we get the Data of a subset into f.i. a grid. Here's the code we use for our JSON services.


The consumed class VMRoot looks like this:

The VMEntitySet is an ObservableCollection which contains VMProjectRegel objects. These are defined like so:

The JSON we receive looks like this:

The DataSource is defined like so:


after executing the dataSourceprojecten.read() the data is available for the main list but how do we specify the fetch for the ProjectRegelsList in f.i. a grid?

This is what I have tried (among many other attempts) to get it to work:

Hi! 
I'm new in Kendo Mobile, but I didn't found the answer on simple from my point of view question: why listview in mobile application does not proper rendered from template? Not listview items, but the whole listview, for example:

if I place <ul> in main div, it works, suppose I do something wrong, please help

I try to make a single page web app. It will contain some grids and forms. Some of the form controls and grids are based on the same datasource. Sometimes I need to get a specific item from the datasource (identified by a parameter) or sometimes I just need every available item from the datasource.

I've solved this problem by adding a parameterMap to the transport of the datasource. Now I'm able to exactly retrieve all items from the datasource, how and when I want. For code example, see rootDatasource below.

In the widgets which I'm using, like Grid, I want to call the read method of the datasource with a parameter specified to retrieve all items from the back-end which match the query 'active' == true. See code example:


And now my problem, this won' work!! I'm really confused, if I just add a reference to the datasource object without directly specifying the .read() method, it just works. (Retrieving all items, including 'active' == false though.) In another form I want to specify some other parameters, so just adding the parameters to my (PHP) back-end just doesn't work.

I've been reading the docs en forums quite extensively to find an answer, didn't find it and I find myself quite stuck right now. Any help will be much welcome. 

I'm trying to validate a <textarea>. Is it even possible to validate any other fields beside inputs? The documentation (http://docs.kendoui.com/api/framework/validator neither http://docs.kendoui.com/getting-started/framework/validator/overview) does not say anything about this.
If <textarea> is not support, how can I achieve validation of multiline text inputs with <input>?

Thx!

Hi,

Can we have range selection ability within DatePicker's calendar. Like i have two datepicker controls i.e., Startdate and Enddate. Both datepickers control will be populated with StartDate's Calender selection. For this I have to make 2 clicks on StartDate's calender for selecting range. Currently, datapicker's calender is closed after having one click so range selection is not possible. Please suggest.

Hey everybody, 
I'm new to kendoUi , and  some problem with MVVM binding with HTML input element.  I try to create person information from <input> element. 
Here is my HTML snippets for collect person information  like "first_name", "last_name", "date_of_birth" etc. 

And I have viewModel , it can read "json" file but couldn't create! 
I think somethings wrong with my save function. 

If someone faced with this problem and got solution! Help me
Thanks

I would like to know how different is to use full source code (for debugging purposes) of Kendo UI MVC wrapper extensions.
So instead of minimized files I would like to deal with full version of .js, .css files and I would like to peek into HTML helper's source code.

Any article/documentation on how to do that. I would like to first try a test solution with a trial version and to understand how it would be different if I would reference source project of MVC wrappers and uncompressed content and script files.

Thanks,
Rad

Any suggestion how to do it?

Thank you,

Hi guys - I'm currently in the process of evaluating the Kendo UI toolkit and im just wondering if you can help me with this problem!

Ive got a KendoDropDownList control and when the selected item changes I update the DataSource on my grid (hopefully).. the problem is when its changed the grid doesn't reflect the changes

View code:
<div class="filter-definitions" style="width: 100%;">
    @(Html.Kendo().DropDownList()
           .Name("filters")
           .DataTextField("Name")
           .DataValueField("Id")
           .HtmlAttributes(new { style = "width: 95%;" })
           .SelectedIndex(-1)
           .DataSource(source => source.Read(read => read.Action("GetUserFilters", "Grid")))
           .Events(e => e.Select("filter_select"))
          )
    <input type="button" value="Add" />
</div>
<div class="filter-grid-container" style="width: 100%; margin-top: 20px;">
    @(Html.Kendo().Grid<GridFilterResult>()
           .Name("filter-grid-results")
           .Columns(columns =>
                       {
                           columns.Bound(p => p.Name);
                           columns.Bound(p => p.DOB);
                       }
                   )
            .Pageable()
            .Sortable()
            .Scrollable()
            .Filterable()
          )
</div>
<script>

and my Javascript

    function filter_select(e) {
        debugger;

        var selectedItem = this.dataItem(e.item.index());

        var filterGrid = $("#filter-grid-results").data("kendoGrid");

        filterGrid.dataSource = new kendo.data.DataSource({
            type: "json",
            transport: {
                prefix:"filter-grid-results-",
                read: {
                url: "/Grid/GetFilterResults",
                contentType: 'application/json; charset=utf-8',
                type: 'GET',
                dataType: 'json'
            }
              , parameterMap: function (data, type) {
                  var values = {};
                  values["filterId"] = JSON.stringify(selectedItem);
                  return values;
              },
                schema: { data: "Data", total: "Total", errors: "Errors", model: { fields: { Name: { type: "string" }, DOB: { type: "date"}}} }
            }
        });
        filterGrid.dataSource.read();
    }

everything looks fine but it just doesn't work and I cant figure out why - can anyone help me with this?


cheers.
