Hi everyone,
I am using Kendo Grid Hierarchy in my ASP.Net MVC application.

For each row in my parent table, i have an option to add a child table.

My parent table is associated with a model. Each row in this parent table has several columns:
- ID
- Name
- Amount
- Button
Every time i add a parent row, all values are empty (ID and Name).

Now, here is my problem:

When my parent row has a child table filled with rows, e need to hide the button in the parent row. 
When i remove my child table, i need to show the buttons again.
I also need to fill a hidden column in the child table, which indicates me who is the parent row.

How can i do this, only in the client side (using javascript)? I want to edit my information inline, and i would like to make a post only after my editing is completed, serializing my table to JSON and sending it to the server.

Thanks in advance.

Best regards

My data structure consists of groups and users with a link table between them.  I have setup an OData data source, where I can do either of the following:

/api/Users?$expand=USERGROUPS
or 
/api/UserGroups?$expand=USERS

I want to display a grid with user groups, and the details row to be a grid of users.

Setting up the grid, I use /api/UserGroups in the data source, and I get all my groups to appear.  Where I am experiencing a problem is displaying the users for a selected group.

At first glance, the data source method to use seems to be /api/Users?$expand=USERGROUPS.  I wrote a function that takes in the value of the selected group from detailInit(e), where e is the USERGROUP.data value, and the group's properties can be accessed:



userDataSource(groupData) returns an array of USERS[], and due to the pageSize attribute, limited to 10.  USERS.  Each USERS element contains a USERGROUPS[] (array) element.

What I would like to return is a list of users where USERS.USERGROUPS.ID == groupData.ID, and have these all displayed in the details grid.

I considered using api/UserGroups?$expand=USERS as the datasource.  In that case I would have to return the array of users within a given group.

Regardless, the filter option I am trying on the data set is not working:

I realize that I could write another data source API that only spits out a list of users (which maybe much simpler), but I would like to know how to use this expanded, navigation content data.

Assistance on this would be appreciated.

I have tried to add an item to treeview when user click expand icon.  But it doesn't work.

Please help.

function onExpand(e) {
  var expandedNode = e.node;
 if (expandedNode.length == 0) {
      expandedNode = null;
}
treeview.append({
text: 'newNode'
}, expandedNode);

}

I need to determine whether an item has children or not.
Any easy way to do it?

Thanks.

Hi there,

I am currently mocking up a demo of a chart. I have attached an image.

I need to replace the numbers on the right axis with labels.

For example,
0 will be Nil
5 will be Bronze
10 will be Silver
15 will be Gold
20 will be Platinum
25 will be Diamond

How can I show labels for that right axis instead of the numbers?

Regards,
Tony

Hello,
after some initial test with Kendo UI and the reading  a book of Freeman about MVC I've decided to put struff toghether... but I've still some hiden point I've to finish analyzing...

First : Does Kendo UI supports Entity Framework (in the specific case IdeaBlade's Devforce implementation)? I've tried with a single Entity and it was ok, added a relational one and the view doesn't load data anymore...

Second: I've read I can use the Async ActionResult for MVC ...beign a fan of It I was wondering how should I load the data with KendoUI , consider for example this ActionResult

    public async Task<ActionResult>  GetClientiAsync([DataSourceRequest]DataSourceRequest request)
        {
            IQueryable<I_CLIENTI> dataResult = await  clientiRepository.GetAllClientiAsync();
            DataSourceResult res = dataResult.ToDataSourceResult(request);

            return Json(res, JsonRequestBehavior.AllowGet);
        }
Third : On the book I've seen it uses the View(<model>)  returned... in some of your example you use Json to return data passing [DataSourceRequest] and as far I've understood it's in order to bind the kendo object on the View... What have I to use so?

Thanks

Hi,

I have just installed the Kendo UI for ASP.NET MVC extensions into my VS 2012 and have a small issue.  It seems in general to have installed ok but when I try to create a Kendo project and I'm shown the Project Configuration Wizard, the drop down box directly underneath the Kendo UI for ASP.NET MVC Project Settings title is empty.  When I click on the download button I get a dialogue box saying "Error retrieving latest version information. Please, try again or contact the Telerik team."

Have I done something wrong?  I'm a bit of a newb at this so any pointers would be greatly appreciated.

Thanks.
Jonathan.

I have 12 calendar on 2 <TR> in my view (6 calendars/TR)
I need the calendar smaller so they all have the style :     .calendar {width: 150px;   height: 200px;}

@(Html.Kendo().Calendar().Name("YearCalendarMay")
.Min(new DateTime(Model.Year.Year,5,1)).Max(new DateTime(Model.Year.Year,5,31))      
 .Footer(" ").MonthTemplateId("cellTemplate").HtmlAttributes(new { @class = "calendar" })                             
        )


I have the problems shown in the picture,probably because I set the Min and Max properties  :

http://img825.imageshack.us/img825/5164/iud2.png


And I try as you suggested to disable the click on title navigation but I'm missing something

$(document).ready(function () {
        $("YearCalendarMay.k-nav-fast").off("click").css("cursor", "default");
        $("#YearCalendarMay.k-nav-fast").on("click", false);
    }); 

I will appreciate some if you can help me please ..
