type ODATA - no additional parameters??

If I set the type of datasource to "odata" additional parameters is not added to the request string. This is my code:

var odataSource = new kendo.data.DataSource({

type: 'odata',

transport: {

read: {

url: server + query, // the service url

data: { //additional parameters sent to the remote service

buchungskonto: function() {

return "'" + $("#search").val() + "'";

}

},

change: function() { // subscribe to the CHANGE event of the data source

$("#results").html(kendo.render(template2, this.view()));

}

});

The resulting request is:

/my.services/SalesData/GetCustomers()?$format=json&$inlinecount=allpages&$callback=callback

As you can see parameter "buchungskonto" is missing. It is a call to a wcf data service, GetCustomers() is mapping to some SP, "buchungskonto" one of the parameters passed to the SP. So the correct call should be:

/my.services/SalesData/GetCustomers()?$format=json&$inlinecount=allpages$callback=callback&buchungskonto='1'

Is this a bug?

Besides that: really great product! BUT, and this is a really big BUT: the documentation is not on the level I'm accustomed to from telerik. I think there is still a lot of work to do for you.

Regards
Heiko

Loading Issues

Hello everyone, first of all sorry for the ambiguous thread name. Since the issue i'm experiencing could be grid, chart or even datasource issues, I'm posting it here. If that is not correct, I apologize a second time.

Following the examples on the site I have built a page with a chart and a grid. With $document.ready I load a few filters and the starting grid and chart, and there's a button right next to the filters to apply any changes to the "dataset" and change what's displayed.

Now, I'm having a little problem and it's that most of the time neither the grid nor the chart load, they appear empty or not at all. Using firebug I can see the requests to my datasource (I'm using a WCF Service and am calling it to return data in json format) have returned data, but the controls don't load.

If that were all, I'd think it was an issue with my configuration, maybe I was missing a property or two, but the strange thing, and what to me is the real issue is that if I refresh the page or click the button enough times, sometimes 2 or 3 times, then the controls will load, so it's not a matter of the data not being in the correct format, but on the next refresh they disappear again. In other words, the kendo controls on the page seem somewhat temperamental and only show up when they feel like it. I have tested with Chrome and even IE with the same results.

If anyone has any idea of why this might happen, I'd appreciate it if you could enlighten me, since it's driving me a tad bit crazy. I will post the code if necessary, just let me know.

Thanks for the time

Editing demo bug : Tabbing on new row

http://demos.kendoui.com/web/grid/editing.html

In this demo, click on 'Add new record' and then type in a product name. Hitting the TAB key does not bring up the next cell (UnitPrice) in edit mode.

After hitting the 'Add new record' button, only if you click on the row using a mouse, it works.

Perhaps a focus-logic issue tied specifically to the mouse click?

Thanks,
Joel

Working asp.net web service with kendo data source and Grid.

I was able to get a simple grid fully functional based on the weapons video at http://www.kendoui.com/videos.aspx called Get Started with the KendoUi Data Source.

I built an .asmx web service in asp.net, and I am posting the code here.

My solution requires you to have jquery.js working on your html page, and for you to set up a .asmx file that supplies web services in JSON format to read, create/update, and delete a list of Japanese weapons. I leave it to the reader to implement their database connection of choice in C# code. Also, one must create the Weapons class in code or have it defined in a web service they subscribe to in the code.

Getting Grid to bind to .asmx web service

Hello,

At our company, we are using the OutSystems platform to publish .asmx Web Services that we can consume in client side software. I am trying to get the KendoUI grid to work with the .asmx Web Services, but I am having trouble getting any data. I am new to javascript and KendoUI, so really dumbing it down can help. Do I need to create a service reference in my asp.net application for the service and then point the grid to that code file, or can I consume the service directly. I read the other posts in the forum about the xml web service, but still can't get it to work.

Here is my code:
