Another question for you lovely Kendo people!
I'm currently struggling to bind more than one function to a Grid, my code is:
Which works fine, but I want this Grid to be a multi-selectable Grid (my own Kendo extension) and can't seem to bind this when I try:
The error displays as "selectableGrid" is not supported by "div" or something along those lines. However, if I try and just use the selectableGrid without the source binding, then it works fine.
Any suggestions, or will this be fixed in a future release?

Hi,
I'm having troubles trying to update a chart: http://jsfiddle.net/luisk/aHFwc/
I'm using chart.dataSource.data(prb);
As you can see in the example, the title is changing but the data source is not.
Thanks!

Hi!
I am unable to retrieve the e.data.id because events from detailExpand is undefined. For detailInit, it's okay. Do you know why? Is there a bug or is this written in this way?
detailInit: function(e) {
console.log(e.data.id);
},
detailExpand: function(e) {
console.log(e.data.id);
},

I would like to display a model window in response to a user clicking on an Axis title of a chart that plot time series data. This modal window would allow the user to adjust some of our chart settings (Xaxis: time period) and (Yaxis: engineering units of measure). I have looked through the forums and documentation but cannot seem to find an event.
Thanks
Paul

Hi,
Can anyone tell me how to retrieve the original object that was bound to the grid when a row is selected.
I attached the following callback to the "change" property of grid. I assume there is a way to fetch the original JSON object from this "arg" parameter.
function onChange(arg) {
.... Need to retrieve the object that was bound to the selected row.
});
Thanks in advance.

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,
Guillaume

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
