I want to get remote data from jsp with json type.
I have modified the example file :  virtualization-remote-data.html as follows :

            <script>
                $(document).ready(function() {
                    $("#grid").kendoGrid({
                        dataSource: {
                            serverPaging: true,
                            serverSorting: true,
                            pageSize: 100,
                            transport: {
                                read: "http://localhost:8060/data.jsp",
type: "jsonp"
                            },
schema: {
data: "results"
}
                        },
                        height: 280,
                        scrollable: {
                            virtual: true
                        },
                        sortable: true,
                        columns: [
                            "OrderID",
                            "CustomerID",
                            { field:"ShipName", title:"Ship Name" },
                            { field: "ShipCity", title:"Ship City" }
                        ]
                    });
                });
            </script>


And my data.jsp as follows:

<%@ page contentType="application/json" %>
<%@ page pageEncoding="UTF-8" %>

<%
try {
    //String json = "[{\"results\":[{\"OrderID\":\"100\",\"CustomerID\":\"122\",\"ShipName\":\"B\",\"ShipCity\":\"D\"}]}]";
String json = "{\"results\":[{\"OrderID\":\"100\",\"CustomerID\":\"122\",\"ShipName\":\"B\",\"ShipCity\":\"D\"}]}";

    response.getWriter().write(json);
} catch(Exception ex) {
}
%>

But the grid have not show any data after loading.

Is there any missing or mistakes in my code?

Thanks!

Hi,

I want to insert the text of the node of the treeview where the user has dropped the node within editor.
Dropping of the node from  treeview to editor is achieved using Kendo DragAndDrop and Kendo Template. I am using template for each node and mark them as draggable. DragAndDrop feature of treeview is disabled as I don't want the nodes to be drag-n-drop within treeview. I am able to add the text where the cursor is within the editor (by using insertHtml) but not where the user has dropped the node.
For example, if user is trying to drop node on line 3 but the cursor is currently on line 1, the text is getting inserted in line 1 and not line 3.

Any idea how to achieve this?

Monish.

How do i wire up a custom grid edit template to have a united kingdom £ and curreny format 999.99 for example.



$('#test').width(250).kendoNumericTextBox({
    format: 'c2'
});

  <script id="popup_editor" type="text/x-kendo-template">
       <input id="test" />
</script>

I know this may seem minor, but it's an issue I'm trying to fix.  If you have an autocomplete and select a value, then clear it with .val(''), then select the same value, the change event doesn't fire.  This is a problem because I'm using the autocomplete with knockout and the observable doesn't get updated.  See this fiddle: http://jsfiddle.net/rniemeyer/Z8yL8/ 

Select red, click Reset, select red again and you'll see that it doesn't log the change to the console.

Aside from the fact that I'm using knockout, the change event should fire if you select something, then clear the value, then select a value.  It only does that when the second value is different from the first, even though the value was empty between them.

Is there any workaround for this issue without waiting for a release?

Hi, 

I have kendo grid that is being binded in the js with a collection from the View Model. as follow when the page loads. 

$('Grid1').kendoGrid({ columns: this.Grid1.Columns, resizable: "true", selectable: "row", sortable: "true", rowTemplate: kendo.template($("#listview-rowTemplate").html()) });

At this point(when the page loads) the ViewModel collection has some default values, later in a callAction of a button event, the ViewModel collection is filled with different information for every column (text, width and others). Looking at the json retrieved the information is correct but the Grid is not being updated until I refresh the page using F5 and the js line of binding is executed again.

The binding is right because in another Grid the ViewModel Collection is filled before the binding and it shows the width, header text and all the rest of the information right.

My question is if the binding for the columns of a grid just work with initial values (previously loaded) and you cannot changes the titles and width or am I missing some details about binding and that´s why the grid is not updating the columns?

Thanks in advance!

I've a grid with a custom template modal window for edit & add. The template has drop down list field defined like below:

<div class="k-edit-label">
            <label for="ColName">Site</label>
</div>
<input name="ColName" data-source="ColNameDataSource" data-text-field="colName" 
      data-value-field="dartSiteName" data-bind="value:ColName" data-role="dropdownlist" />

When I edit a row and change the value of the drop-down it shows correctly in the grid.

But if I Add a row and change the value of the drop down it shows up as [object Object]. Does anyone have any idea what could I be doing wrong?
Thanks.

I have a hierarchical grid with 3 levels, in which the 2nd and 3rd levels are bound on the client side during expansion of the row through the OnDataBinding ClientEvent.

Sample code for binding I am doing:

    function detailGrid_dataBinding(e) {
        if ($(this) != undefined) {
            var grid = $(this).data("tGrid"),
                masterRow = $(this).closest("tr.t-detail-row").prev(),
                dataItem = $("#Status").data("tGrid").dataItem(masterRow);

            grid.dataBind(dataItem.Details);

            e.preventDefault();
        }
    }

However, when I apply the sorting/filtering/paging options to grid in the detail view, the visualization for the feature shows up but they don't function.

Is this a known issue?

I have a Grid connected to DataSource and displayed on clipboard01.jpg
When I click on the Calculate button, I collect some the Grid's data and send it over to the server with an Ajax call
I return Json with some calculated values for the MTM field, which I'm adding to the grid...

    $.ajax({
        type: "POST",
        dataType: "json",
        data: unwindDataToPostObj,
        url: direction
    })
    .done(function (response) {
        var grid = $("#gridAssoc").data("kendoGrid");
        grid.dataSource.data(response);
        grid.refresh();
    })
    .fail(function (jqXHR) {
        console.log("error");
    });

Please look at picture: clipboard02.jpg now
The formatting for the Trade Date & Settle Date is now broken, although it was declarative set by the book.

    // ** Grid widget
    $("#gridAssoc").kendoGrid({
        dataSource: CFDUnwind._assocTradesDataSource,
        navigatable: true,
        selectable: "single",
        height: 300,
        resizable: true,
        sortable: {
            mode: "single",
            allowUnsort: false
        },
        columns: [
            { field: "Strategy", title: "Strategy", width: 60 },
            { field: "ImagineSNum", title: "ImagineSNum", width: 50 },
 
            {
                field: "TradeDate", title: "Trade Date", width: 48,
                template: '#= kendo.toString(TradeDate,"MM/dd/yyyy") #'
            },
            {
                field: "SetlDate", title: "Settle Date", width: 48,
                template: '#= kendo.toString(SetlDate,"MM/dd/yyyy") #'
            },

...etc....

1. Why is the formatting not obeyed?
2. In other words how do I manually set the data on the grid and preserve any formatting already set on the columns?

This is probably simple, but I've not found a solution. I've a ground declared like so:

    <div id="grid" 
         data-role="grid" 
         data-bind="source: tasks" 
         data-columns='[{ "field": "taskId", "width": "150px", "title": "Id" }, ... ]' 
         data-pageable='{ "pageSize": 10 }'
         data-groupable='[{ "field" : "completionStatusDescription", "aggregates": [{"field": "taskId", "aggregate": "count"}] }]'
        >
    </div>

This is bound to a view model and all works fine except for the grouping. Is the above the correct format? I couldn't find explicit docs on this and just guessed, which is probably why it isn't working. The grouping works in the UI, although I can't configure the aggregates.

Is this possible, or have I just got the synax wrong?

Thanks
