I have a case where the datasource object is passing a blank $filter param. When using the MVC4 RC Web-api it throws an error because the filter is blank. 

Here is a sample URL the datasource is calling:
http://localhost:3046/api/clients?%24inlinecount=allpages&%24format=json&%24top=50&%24filter=

What appears to be happening is that it only adds the blank filter if I clear out the search criteria  (right now I just have this bound to a combo box). So when I type in something to the combo, it makes the call to the server, filters correctly. But if I clear that, it will pass a blank filter.

How can I intercept that to make sure it isn't even passing the filter?

When we press the enter key without selecting any item from the opened list area of an Autocomplete kendo plug-in, we may get an error 
"Line: 217. Error: Unable to get value of the property 'index': object is null or undefined"
in IE9. This is because the "item" object of the passed-in parameter "e" is null. The following fixed me this issue.

if (e.item == null) return;
                var dataItem = this.dataItem(e.item.index());
I hope that a developer like me, makes use of this.

After setting the animation to false, try to expand the panel contains some sub-panels and then collapse it and then expand it again, the sub-panels within this panel will not work properly. 

I am trying to get DnD to work from a TreeView to another component.  

How do I get the item from the TreeView on drop?  I have tried e.draggable, but I cannot find the item there.  
     
I have also tried calling $("treeview").data('kendoTreeView").select(), but it only returns the html and not the item.
This method also has the problem where if the item is dragged, but not selected, select returns nothing.

Thanks for the help.

Hello! I am new kendo ui and i am developing a mobile web application for an institute. At first stage, I want to show all the courses which contains 5 columns(eg name, details...). My question is how can I return these data to data reader and bind to listview?

Thanking you in advance!

Hi,

I am trying to create a ListView of items. I am trying to make it such that when a user clicks on the "rowdelete" detail button, that particular row gets updated or deleted in the dataSource, and the ListView gets synced to that.

I declare my list view with a template like this:

<ul id="flat-listview" style="font-size: .8em"></ul>
<script type="text/x-kendo-template" id="customListViewTemplate">
${name}: ${qty}<a data-role="detailbutton" data-style="rowdelete" data-click="deleteItem"></a>
</script>

The functions to refresh the ListView and add items to it are as follows:
<script>
function reinitListView() {
$("#flat-listview").kendoMobileListView({ 
dataSource: kendo.data.DataSource.create({data: dataList}), 
template: $("#customListViewTemplate").html(),
});
}

function addToList(item) {
for (var i = 0; i < dataList.length; i++) {

if (dataList[i].name == item) {
dataList[i].qty++;
reinitListView();
return;
}
}
dr = new Object();
dr.name = item;
dr.qty = 1;
dataList.push(dr);
reinitListView();
}
</script>

I tried writing a function called deleteItem (called when the button is clicked), but I don't know how to access the list view row from there. 

Hello, Its been week and still no luck on dropdown and finally I'm throwing up my towel. I hope you can help me on this.




Please help! thanks!

I would like clicking on a selected node to do the same thing as clicking on an unselected node.
Triggering the "select" event even it its selected would be fine but any other solution
to trigger SOME event if the node is already selected is fine too.

I added a datepicker control to a grid for edit mode. When the updates, it displays a long format time string. I would like to format the time as a short date string, but I have not found the event to delegate. The code below demonstrates the problem:

            <div id="grid"></div>

            <script language="javascript" type="text/javascript" >

                $(document).ready(function ()
                {

                    $("#grid").kendoGrid({
                        dataSource:
                        {
                            data:
                            [
                                {Employee:"Joe Jones",Dept:"Sales",Job:"Account manager",DateVal:"1/2/2012"},
                                {Employee:"Samantha Smith",Dept:"Marketing",Job:"Design",DateVal:"2/3/2012"}
                            ]
                        },
                        pageable: true,
                        height: 455,
                        filterable: true,
                        sortable: true,
                        scrollable: { virtual: false },
                        selectable: 'row',
                        columns: [
                            { field: "Employee", title: "Employee" },
                            { field: "Dept", title: "Department" },
                            { field: "Job", title: "Job" },
                            {
                                field: "DateVal",
                                title: "Date Hired",
                                editor: function (container, options)
                                {
                                    $('<input id=\"' + options.field + '\" />').appendTo(container)
                                    .kendoDatePicker({ format: "MM/dd/yyyy" });

                                    var datePicker = $("#DateVal").data("kendoDatePicker");
                                    // bind to the close event
                                    datePicker.bind('close', function (e)
                                    {
                                        var datepicker = e.sender.element.kendoDatePicker()
                                        var d = new Date(datepicker.val());
                                    });

                                }
                            },
                            { filterable: false, command: ["edit"], title: "&nbsp;", width: "210px"}],
                        editable: "inline"
                    });

                });

</script>

Click "Edit", then a date from the datepicker control, then look at the resulting time string in the grid.
Sorry if I posted this in the wrong forum before.

I created a datepicker column in the grid for edit mode. It works, but when the grid gets the date from the datepicker, the time string is in long format. I would like to be able to change this to a short date, but I have not been able to determine how to intercept the update. Past the code below into a page to see what happens. How can I change the date format in the grid to show a short date after editing? Thanks.

           <div id="grid"></div>

            <script language="javascript" type="text/javascript" >

                $(document).ready(function ()
                {

                    $("#grid").kendoGrid({
                        dataSource:
                        {
                            data:
                            [
                                {Employee:"Joe Jones",Dept:"Sales",Job:"Account manager",DateVal:"1/2/2012"},
                                {Employee:"Samantha Smith",Dept:"Marketing",Job:"Design",DateVal:"2/3/2012"}
                            ]
                        },
                        pageable: true,
                        height: 455,
                        filterable: true,
                        sortable: true,
                        scrollable: { virtual: false },
                        selectable: 'row',
                        columns: [
                            { field: "Employee", title: "Employee" },
                            { field: "Dept", title: "Department" },
                            { field: "Job", title: "Job" },
                            {
                                field: "DateVal",
                                title: "Date Hired",
                                editor: function (container, options)
                                {
                                    $('<input id=\"' + options.field + '\" />').appendTo(container)
                                    .kendoDatePicker({ format: "MM/dd/yyyy" });

                                    var datePicker = $("#DateVal").data("kendoDatePicker");
                                    // bind to the close event
                                    datePicker.bind('close', function (e)
                                    {
                                       // See what the datepicker is returning:
                                        var datepicker = e.sender.element.kendoDatePicker()
                                        var d = new Date(datepicker.val());
                                    });

                                }
                            },
                            { filterable: false, command: ["edit"], title: "&nbsp;", width: "210px"}],
                        editable: "inline"
                    });

                });
