Do you have any plans for canvas based visualization components? 

Infragistics is demoing html5 canvas based charts with 500,000 data points where you can zoom in on specific points.  Just wondering if a similar story exists for SVG, performance wise does this translate?  Did you do any published analysis on this?

In the past, the recommended LOB path would have been a plugin (silverlight) to show this amount of data.  Now that this is available with a canvas it is tempting for LOB applications.

Hello,

Before the new release, if i wanted to get the JSON object model in a data source, i did :
But now, in the JSON string i have also a "_events" node inside it.

So, how can i get real data ?

Here the jsFiddle : http://jsfiddle.net/eyAkP/13/ 

Best Regards,

 I have the latest version of KendoComplete, and a grid that I have enabled grouping with a remote data source
I can group, but the arrow switch at the left of the group is missing, which means I cannot expand or
collapse the group. (this happens no matter what theme I choose).


I also have selectable enabled (by full row) with multiple items, and I would like to be able to press 
the group heading and select the entire group at once. Any ideas?

                  $("#grid").kendoGrid({
                        dataSource: myRemoteData,
                        groupable: true,
                        scrollable: true,
                        sortable: true,
                        pageable: true,
                        selectable: "multiple, row",
...

Hi,

I'm trying to get Server Aggregates working on my grid and I can't seem to get them to show up.  Server grouping, sorting, and filtering are all working until I return the aggregates and then the grid no longer renders the data.  

There seems to be an issue in writing the group footer.  I get the error on the call to that.groupFooterTemplate(group.aggregates) inside the grid's _groupRoiwHtml function: "Uncaught ReferenceError: sum is not defined".  I assume its either my groupFooterTemplate configuration or the actual aggregates I'm returning, but I can't figure it out.

Once I've got this working I'd also like to get the grid footer aggregates working, but I'm not sure where those are getting pulled from either. 

I've put some of the relevant configuration below:

DataSource.schema.model

DataSource.group

DataSource.aggregate

Grid.columns

DataSource.schema.groups gets set to this:

Also, it would be awesome to have a sample out there that showed how to implement server-side everything (sort,filter,group,aggregates) so one could get an idea what the setup would look like...

Thanks!
Matt

Hi

thanks

I have a Kendo Grid bound to a Wcf service that follows the example found in https://github.com/telerik/kendo-examples-asp-net/tree/master/grid-wcf-crud 

This sample is based on a Wcf using <enableWebScript />.  My service's Update receives the DTO from Kendo Datasource and updates perfectly, returning {"d":null}, exactly as does the grid-wcf-crud project's Product.cs Update service method.

Back in the browser, the in IE9, an error is experienced in kendo.web.js:
  Line: 5128
  Error: Unable to get value of the property 'length': object is null or undefined

it is likely happening in the code that is seeking to mark the rows as not dirty, because they are included in the next Save invocation, and are still marked with a red tic mark.

This error does not happen in Chrome.  This error does not happen in IE  when running the grid-wcf-crud.  I cannot find any difference between my implementation and the sample.  web.config is virtually the same between my app having the error compared to the grid-wcf-crud sample that does not have the error.  Any ideas?

The code in kendo.web.js that is hitting the error follows, with the error on the last line where data is null in " length = data.length ":

    var DataReader = Class.extend({
        init: function(schema) {
            var that = this, member, get, model;
            schema = schema || {};
            for (member in schema) {
                get = schema[member];
                that[member] = typeof get === STRING ? getter(get) : get;
            }
            if (isPlainObject(that.model)) {
                that.model = model = kendo.data.Model.define(that.model);
                var dataFunction = that.data,
                getters = {};
                if (model.fields) {
                    each(model.fields, function(field, value) {
                        if (isPlainObject(value) && value.field) {
                            getters[value.field] = getter(value.field);
                        } else {
                            getters[field] = getter(field);
                        }
                    });
                }
                that.data = function(data) {
                    var record,
                        getter,
                        idx,
                        length,
                        modelInstance = new that.model();
                    data = dataFunction(data);
                    if (!isEmptyObject(getters)) {
                        for (idx = 0, length = data.length; ...........

I am popping up a window and the opening and closing works fine, but the content while simple isn't all rendered. The DIV for the window is below. I have an ordered list with four items and 4 input buttons.

The ordered list, seems to be converted to paragraphs and the input buttons are just plain text. The H1 and the SPAN work as expected. Inspecting them in Firebug, shows that they have the UL, LI tags. The behavor is the same in IE9, Firefox, Chrome and Opera.

Thanks

I have a Grid binded to a DataSource.
I handle the DataSource Error event this way:


I try to delete a row that throws an Exception. The first time, it's ok ; I see the error and the row is back again.
If I try to delete the same row again, I see in Firebug that 2 requests are made, for the same Id.
It I try to delete the same row again, 3 requests are made. etc. etc.

What am I doing wrong ?

jQuery Mobile supports posting <form> tags automatically using AJAX:
http://jquerymobile.com/test/docs/forms/docs-forms.html 

Does Kendo UI Mobile support this? I can't find any documentation/examples. Do we have to implement our own AJAX methods for each form?

Hi,

I’am currently testing Kendo UI Grid.  Our product uses Telerik and would like to move towards Kendo.  I have a general question on the Grid control using Row templates.

Let say I use the following row template that I would like to use with a Grid.  The first cell would be bound to the “Field1” of my object.  The second cell is a link that points to a URL bound to “Field2” of my object.

<script id="MyRowTemplate" type="text/x-kendo-tmpl">
<tr>
  <td>${ Field1 }</td>
  <td><a href=”${Field2}”>click me</a></td>
</tr>
</script>

My question is the following.  How would I insert some logic to remove the link if the “Field2” my object set is empty.
In pseudo code I would like to achieve the following.

If myObject.Field2 = “” then
  Do not generate a link
Else
  Show the link with the Url pointing to MyObject.Field2

In other words I’am trying to find a way to have more control on the html generated when binding fields to a grid.  Not sure if using a Row template is the way to go in my case.  

Thanks in advance.
