Hi,
I'm working with Kendo grid with data grouping. But the collapse/expand button not working at all and the triangle shape different from the demo sample.
I suspect that something wrong with the css or .js file, but have no idea which one is.
This is how I define them in my layout :
   

and this is how my grid code :


Help pleaseee.

I have a data grouped by a column with summations in a footer template. When I add the "create" command to the grid column nothing happens. How do you add a new row that's part of a group?

Hello,
I appreciate any help. 
We are using 2012.2.723. 
 Just found sample  and pasted into my project; still having the same error what I have in my code:
Uncaught Error: Syntax error, unrecognized expression: tr:not(.k-grouping-row) > td:not(.k-hierarchy-cell,.k-detail-cell,.k-group-cell,.k-edit-cell,:has(a.k-grid-delete))  
Is it a wrong version?

This is sample from forum just selects row and gives an error above:
 <div id="grid"></div>

Hello 

Firstly, excuse any errors in the code. JQuery is new to me.

The data is coming back from the server in Json(result). Now I need to bind it to the grid (and obviously the way I am trying to do it is not working). Do I need to specify a schema for the dataSource? Can this not be "read" from the Json data?

Hello,

I've been running into an issue where menus (those on grids and otherwise) are not fully closing or opening.  This happens maybe every 5th click.  It is only seen on the Chrome browser, right now, but it really looks like a problem.  I am using the lastest release of kendo.web (2012.2.710) and have tried several different styles.

Oddly, the demos on the site look fine, but as soon as I do the exact same thing on my site, the menu issue appears.

I must be doing something wrong, but what could it be.  I am out of options to troubleshoot.

Thanks a ton in advance,

Zach

Hi,

I have a kendo grid, and it's column definition is like this:

ColDef = [{
    field: "apple"
}, {
    field: "banana"
}, {
    field: "orange"
}, {
    field: "papaya"
}, {
    field: "grapes"
}];

Now, depending on certain conditions, i need to change the order of these columns. If the user selects "orange" from a drop down, i want that column to appear first and then the other columns. How can i achieve such functionality? please help.

Regards,
Khushali

Hi, I've just started with KendoUI and I'm stuck already!

I created this simple page and it works fine in IE9, but in Chrome I have some strange artefacts like blurry text or wrong positioning of the button or leftovers like this screenshot

any ideas? thanks

I'm trying to get a HierarchicalDataSource from my server, but I need to pass in specific values.  I can't figure out how it's done and have tried following DataSource's documentation. 

It breaks when it tries the .read().  When I specify "read" it says "TypeError: Illegal invocation ", when I specify "create" it says "Cannot read property 'data' of undefined ".

I'm currently doing:

    var param1= ...;
    var param2 = ...;

        var dataSource = new kendo.data.HierarchicalDataSource({
            transport: {
                read: {
                    url: "/Home/GetStuff",
                    dataType: "json",
                    data: { param1: param1, param2: param2 }
                }
            },
            schema: {
                model: { id: "id", hasChildren: "hasChildren", children: "items" }
            }
        });


        dataSource.read();

My server method is public ActionResult GetStuff(Guid param1, Guid param2)

As per DataSource's docs, I tried using "create", as well as trying create: function(options) {... .ajax... }.

Hi,

I've been working on a problem for awhile and am now seeking some help.

This involves a view model with a remote datasource and HTML binding of a template.

I'm using a combination of Bootstrap, Kendo, ColdFusion and SQL Server for my app.  Everything is working well, but I have run into an issue binding a viewModel with an HTML template that is styled using Bootstrap.  I'm pretty certain that the Bootstrap isn't interfering, but it's worth knowing that I am using it.

I am getting an error that "source.parent is not a function" which occurs in line 7405 ("source = source.parent()") of kendo.web.js.

I have a feeling that the problem with the remote datasource, because if I replace it with a local datasource, it works fine.



The workshops source in the vm is not automatically called and isn't available on page load.  If I force a read, I still get the error.  Sorry for all the extra fields in the data, the 4 fields in the model are in there, trust me :)
