I'm just evaluating the Kendo grid for an upcoming project and I'm hunting for demos for the functionality that I need.

I have created a grid in an asp.net razor view that takes a viewmodel.  A couple of the model properties are enums which display nicely but when clicking into the cell just render a text box with the enum value (1,2,3,etc).

Does anyone have a demo where the edit field is an appropriate dropdown rather than the raw value of the enum?

Thanks in advance :)

For reference the model and view I'm using are:

Hello,

I have added an example of the problem, see:
http://jsbin.com/edamuj/427/edit

I have an editable grid and want to connect it with an editable datasource. This works if I create the grid with the datasouce available. However in my solution I am not sure when the js for the datasource is rendered but if it is rendered I register it in a kendo observable array. A function to set the the grids datasource is bound the change event of the observable array. After this function fires I would like the grid to show the data. Unfortunately this is not working. I simplified the problem and added it as an example. Can someone explain to me what I am doing wrong here?

Hello, I need to fill TreeView Object from asmx webservice.
The data must be:
Main
    DepA
         A
             A1
    DepB
        B
          B1
..............................................................
I don't need to get all data for tree creation for the first time.
I need append the nodes, from the webservice and 'refresh' the tree
The node must include the ID & Name.
How I must organize the WebServise? What format of data must be returned?
How I could append new node and recreate tree?

I have a grid where the columns are dynamic.  By default (no schema set) all the columns are strings which causes the sorting to not be that helpful.

I use a web service that returns json to get the data for the grid, can I define the column types there or would that be a separate call?

Once I know the column types is it possible to set the column format based on the type? 

I have some code that defines the field type for columns if I know their exact name but that isn't very practical because there are many different possible column names.
I also have some code that sets the template or format for a given column but it is also hard coded and not scalable.
Any help would be appreciated. 

I am using the Kendo grid in remote virtualization mode for a very large data set. My stored procedures are aware of paging and capable of returning partial data fetches, instead of returning all rows for every request. Each service call will return exactly one page worth of data (100 records) based on my start/end markers. I use the request object to calculate the appropriate offsets for the next pull.

There are several 1000 records in my total record set, so I would like to avoid pulling all the data for every request.

However, for some reason I am not able to use ToDataSourceResult to build the JSON object that the grid expects to be passed back from my virtualization action:

EX:
public ActionResult Virtualization_GetProducts([DataSourceRequest] DataSourceRequest request, int productId)
        {
   int startIndex = (request.Page - 1) * request.PageSize + 1;
            int endIndex = startIndex + request.PageSize - 1;
            var result = service.GetProducts(productId,startIndex,endIndex);

            return Json(result.ToDataSourceResult(request));
        }

The result that I get is {"Data":[],"Total":100,"AggregateResults":null,"Errors":null} -- even though I get back the expected result from the service.

If I instead return all the data without using startIndex/endIndex the grid is able generate the correct JSON.

All the examples I've found (including your demo) involve pulling all the data in your data source every time. Is there a way to make this work with a data source that supports its own paging like above?

Hi there,

slowly getting used to this MVVM thing but I still have some problems.

I set up my viewmodel as a kendo.observable and also set a datasource and a method:

My orders (the list) is displayed without any problem (tho it took me some time to accomplish that) 
Now I'm trying to display the corresponding details for each order in my detailsView:

Nothing happens...
When I am moving the showOrderDetail out of my viewmodel (as function showOrderModel(e){ ...} everything works.
But I want to capsule the corresponding functions of a model (which is showing details) into that model. Or am I missing sth?

Hope someone can point me into the right direction.
Thx

I have two views that use the same data for different purposes (only showing the one with a problem below, they are basically the same thing). They each have a button group at the top and bottom of the list.  The problem I have is when I scroll to the bottom of one of my groups such as the A-E group, then click one of the button group buttons to load another set, it can be quite a bit shorter and nothing shows in the view.  I have to "double-click/drag" on the surface to get it to "come down" and show the list.  So I have been trying to get the scroller reset to work.  Scroller reset works fine in other areas of my app where the data-show function has access to the view.  But the data-select from the button group does not seem to pass the view to the function.  At least that is what I see from your sample code for button groups and data-select.  So when I try to get the view in the function from data-select, it works for one of the views but not for the other.  The one that does not work executes a data-show function from a different view, or rather it does the scroll work, but then also calls this unrelated function which renders a different view for another part of the app.  The extra function it calls is mobileCompanyPackageDataBind which is for the view in the code below the one I am working with.  If I use the Back button it shows the correctly scrolled alpha group I wanted, but there has got to be something wrong that it does this extra thing.  What is going on and can I work around it?



EDIT:
I figured out a work around.  I save the appropriate view similar to above but do the scroller and scroller.reset in the change event of the datasource.  That seems to consistently work.

Hi, I am having problems using an instance of a kendo.Data.Model in a HierarchicalDataSource.

I tried this simple model for a folder object:

var folderModel = kendo.data.Model.define({
    id: "Id",
    hasChildren: "HasChildren",
    children: "Children",
    fields: {
        Id: { editable: false, nullable: true },
        Name: { validation: { required: true} },
        ParentFolderId: { editable: false, nullable: true }
    }
});

Then created a simple data source using that as the model:

var folderStore = new kendo.data.HierarchicalDataSource({
    transport: {
        read: {
            url: "/Folders/",
            dataType: "json",
            type: "POST"
        },
    },
    schema: {
        model: folderModel
    }
});

The datasource is then used to bind a TreeView.

$(function () {
    $("#folderTreeView").kendoTreeView({
        dataSource: folderStore,
        dataTextField: ["Name"]
    });
});

This fails and the treeview is not bound.

However, it does work if I use an inline approach when defining the datasource:

var folderStore = new kendo.data.HierarchicalDataSource({
    transport: {
        read: {
            url: "/Folders/",
            dataType: "json",
            type: "POST"
        },
    },
    schema: {
        model: {
            id: "Id",
            children: "Children",
            hasChildren: "HasChildren"
        }
    }
});

Even if I simplify the model down to:

var folderModel = kendo.data.Model.define({
    id: "Id",
    children: "Children",
    hasChildren: "HasChildren"
});

I cannot use it in the datasource.

Must be missing something here, please advice. Would like to use the model for CRUD operations elsewhere and want to use the same model in the treeview.

Hi, 

I am unable to send parameters for a DELETE (destroy) as urlencoded (it gets sent in the request body instead). I am able to send parameters for GET as urlencoded, but not for DELETE. I have the following defined in a datasource below.

Any ideas?

Cheers,
Vaughn
