Is there a way to use not like as a filter operator for a Kendo Datasource. Similiar to SQL { WHERE x not like '%y%' }?

Hi,

How to fire backbutton action with javascript on my own button (ie <a>back</a>).

Hi there,

I am doing a listview application which gets data from the server and - onclick - displays detail data for the current listview item.
When loading the first page of data from the server (the server id paging) everything works flawlessly. On clicking / touching the item the details page is provided with all the data from the record.
However, after scrolling down and (automatically) loading the 2nd page I am just able to get details data for the items from the 2nd page when clicking / touching them but not from the previous 1st one anymore. The details pages of the first page are simply empty.

Is this happening by design? Or am I doing sth. wrong? And if it's not my fault, will this be addressed in any next release?

regards,
Erik

Hello,



I use MVVM to bind a ListView to my viewmodel and also the item template uses the MVVM pattern. The ListView dataBound event is binded to a function on my viewmodel.

The problem is that, when my dataBound function is called, the items exists, but are not yet binded to the data.

It appears that the item binding is triggered in the ListView.refresh function by calling the trigger('dataBound') function. There are actually 2 dataBound events, my event and an event of the binding system. And it appears my event is called first.

In my opinion it should be ensured that the binding event is always the first one executing.



I can workaround it by attaching my dataBound event after the binding of the ListView ( with listview.bind('dataBound', function (e) {...}) ), but that is against the MVVM pattern.

Hello,



See this fiddle: http://jsfiddle.net/JaapM/PtQB7/

The third column has values, so a DropDownList control is generated for it.

When you click in the first column, the editor is show. Then tab to the second column. The editor is displayed also.

Then tab to the third column. The editor (dropdown) is not displayed. It is just a focused cell. When pressing Enter or F2, the dropdown is displayed, but the table cell in the background this has the focus. Also you can navigate away from the cell with the arrow keys, this is not possible in the other columns.

Hi,

I'm using the ListView control to create a Heatmap and it's working perfectly, except I'm trying to limit the height of the control to 250px, but setting "height: 250" doesn't do anything.  I'm not used this control before and I know from using the grid this would work.

Currently I'm loading in about 500 items and it's making the whole page scrollable, but I want to have the control scrollable within it's own div (just like the Grid control).  BTW, I don't want to use paging.

Can someone please help?

Hi,

Based on your beta demo here: http://demos.kendoui.com/beta/web/treeview/odata-binding.html 

I have put together the following:

var Folders = new kendo.data.HierarchicalDataSource({
        transport: {
            read: {
                url: function(opt) {
                    if(opt.UID == undefined) opt.UID = 0;
                    return kendo.format("/api/GetFolders/{0}",opt.UID)
                    },
                type: "GET",
                dataType: "json"
            }
        },
        schema: {
            model: {
                hasChildren: function() {
                    return true;
                },
                id: "UID",
                children: Folders
            }
        }
    });


    $("#testTree").kendoTreeView({
        dataSource: Folders,
        dataTextField: ["Title"]
    });

As you can see I am using a fairly ugly hack for the initial UID setting. But it works with my data.

Since there is no documentation yet (that I can see) can you advise if there is a better way of doing this? In particular I'd like to have more than one TreeView on screen (sharing a single data source if possible) and be able to specify at runtime where each TreeView should 'start'.

Thank,

Mark.

Hi,

I have a very simple tree view by using html tags as below:

I try to use jQuery to loop through the data for each level.

When I called the chidlren("li") function, it's supposed to return the nodes in next level.

But it returned null.
 

    <ul id="treeview">
        <li data-expanded="true">
            <span class="k-sprite folder"></span>Active Adapters
                <ul>
                    <li data-expanded="true">
                        <span class="k-sprite folder"></span>Adapter 1
                                <ul>
                                    <li><span class="k-sprite html"></span>
                                        <input type="checkbox" id="1" style="margin-bottom: 5px;" /><a href="#" class="bootstrap-custom-link1">Sub1</a></li>
                                    <li><span class="k-sprite html"></span>
                                        <input type="checkbox" id="2" style="margin-bottom: 5px;" /><a href="#" class="bootstrap-custom-link1">Sub2</a>   </li>
                                </ul>
                    </li>
                    <li data-expanded="true">
                        <span class="k-sprite folder"></span>Adapter 2
                                <ul>
                                    <li><span class="k-sprite html"></span>
                                        <input type="checkbox" id="3" style="margin-bottom: 5px;" />&nbsp;<a href="#" class="bootstrap-custom-link1">Instance 1</a></li>
                                    <li><span class="k-sprite html"></span>
                                        <input type="checkbox" id="4" style="margin-bottom: 5px;" />&nbsp;<a href="#" class="bootstrap-custom-link1">Instance 2</a></li>
                                </ul>
                    </li>
    </ul>
