Please tell me the way to bind the tree view using data source.
I am using the below code to bind the tree view,I am not  sure I am on the right track.


@(Html.Kendo().TreeView()
    .Name("treeview").DataTextField("Name")
    .DataSource(dataSource => dataSource
        .Read(read => read
            .Action("GetFolderTreeData", "Dashboard")
        )
    ) 
    
    
)

Hello,

I am calling a Window that populates using a Controller Action Partial View.   My window will contain cascading dropdowns.  If I add a serverfiltering with a datafilter to my datasource I get a javascript error saying it can't find said method.   When I remove the filter the box populates but Autocomplete doesn't work properly.    If I change it to clientside filtering it works fine but I need to be able to add a group filter.     Is Server filtering not available inside a Window control ?

I prepared a sample project to illustrate the problem. 

Thanks,
Carrie

Hi all,

I have implemented Kendo MVC Upload to our ASP.NET MVC 4.0 web app. Unfortunately we get many  dropped uploads. 

The upload method is executed but it contain empty file list and Request.ContentLengh and Request.TotalBytes do not match. Do you have any idea why this happens?

 [HttpPost]
public ActionResult UploadFile(IEnumerable<HttpPostedFileBase> clientUpload, [OptionModelBinder]IOptionViewModel formData)
{
//our action
}

Hi,
I am trying add tabs into an existing tabstrip and it works as expected. But when the number of tabs increase it goes to the second line. Is there a feature that will place the tabs on the same line.
Thanks in advance

I would like to be able to map a DataSourceResult to a ViewModel in my controller class, is this possible?

I have a pretty normal MVC application with a ViewModel

And a normal Grid in razor
My controller has the following action for AJAX binding for filtering.


My service class has the method for getting the users.

This code returns a Javascripts serialisaztion error - Object connection closed. I presume this is because the JSON call in the controller is trying to serialise the entity framework object perhaps trying to perform some kind of lazy loading but of course the connection to the DB is closed as it's in a 'Using' statement.

What I'm trying to achieve is a way to return a ViewModel to the grid from the controller action. 

I can force the DataSourceResult to map to a POCO using the following code in my service class. I do NOT want to use a ViewModel in my service class, only the controllers should be aware of the ViewModels.
But then I still need to map the DataSourceResult to a ViewModel in the controller.

Is this possible?

I have few grids and I do filtering and reduce the standard operators. Code below.
I also use the Swedish language. However all the standard operators show up for the columns. (Extra(false) works)
When I remove the Kendo.Mvc.resources.dll everything works as expected.
The version of the dll is 2013.2.918.340 and I have the same version for the Kendo.Mvc.dll
The translations works fine when the resources are available but I like to reduce the operators.
Is this a bug? 

I updated today to the new Q2 2013 service pack, now all editor windows show text rather then icons.

Hi. I am using Kendo UI in an ASP.NET MVC 4 application (using the Razor view engine) and I keep hitting a problem with how Kendo is auto generating the model structure for the rows in a grid.

I have a view and the model for that view contains a list of items, called Bricks, and then each Brick contains a list of items called BrickQualityMetricDtos. I created an editor template for the Brick class so that the MVC framework would properly name all of the fields. Within that editor template I have a Kendo UI Grid that I am using to display/edit the list of BrickQualityMetricDto classes. Two of the fields in that class are dropdowns, which I am using ForeignKeyColumns for, but every time I edit a row and then select a value of one of the drop downs I get this javascript exception:

"Unable to get property '0' of undefined or null reference"

This exception is getting thrown by this anonymous function:
function anonymous(d,value) {
d.Bricks[0].ExclusionReasonPK=value
}

The exception is being thrown because there is no Bricks member of "d" and therefore it cant get the "0" property. As far as I can tell "d" is an object that represents the model for the row that I am editing because it has fields "ExclusionReasonPK", "BrickSectionPK", "LengthExluded", and "PK" which are all of the fields of the BrickQualityMetricDto class. So the problem is that since the grid is in an Editor Template it is throwing this non-existent Bricks property onto the "d" object before it tries to access the actual properties of the object.

Can you please advise how to get around this limitation? I need to be using an Editor Template because if I don't then I won't get all of the other data fields in my form when I submit the form to my controller action.

Below is the code for my grid, but I am pretty sure that everything is correct in there.

@(Html.Kendo().Grid<BrickQualityMetricDto>()
.Name("BrickQualityMetrics_" + Model.Index)
.Columns(columns =>
{
columns.ForeignKey(e => e.BrickSectionPK, Model.BrickSections, "PK", "Name").Title("Section");
columns.ForeignKey(e => e.ExclusionReasonPK, Model.ExclusionReasons, "PK", "Name").Title("Exclusion Reason");
columns.Bound(e => e.LengthExcluded).Title("Length Excluded (mm)");
columns.Command(command => { command.Edit(); command.Destroy(); });
})
.Events(events =>
{
events.Edit("onBrickQualityMetricsGridEdit");
})
.ToolBar(toolbar => toolbar.Create().Text("Add"))
.BindTo(temp)
.Editable(editable => editable.Mode(GridEditMode.InLine))
.DataSource(dataSource => dataSource
.Ajax()
.Events(events => events.Change("onGridDataSourceChange"))
.Model(model => model.Id("PK"))
.Create(update => update.Action("BrickMetric_Create", "Brick"))
.Update(update => update.Action("BrickMetric_Update", "Brick"))
.Destroy(update => update.Action("BrickMetric_Destroy", "Brick"))
))

EDIT: I just checked again and this problem is not limited to Foreign Key Columns. It is happening on the standard Bound column as well.

Also here is a similar post from the old ASP.NET MVC Telerik forums. It looks like the problem was never fully resolved though: http://www.telerik.com/community/forums/aspnet-mvc/grid/problems-with-grid-in-editor-template-in-collections.aspx

I just downloaded and installed the 2013.2.716.340 version of the ASP.Net MVC Kendo Complete package.  Then I started a new MVC 4 project with .Net 4.5 in Visual Studio 2012 Update 3.  I ran the new project without touching a single piece of code and get the following javascript error.

Unhandled exception at line 10, column 180 in http://localhost:62497/Scripts/kendo/2013.2.716/kendo.aspnetmvc.min.js0x800a138f - Microsoft JScript runtime error: Unable to get value of the property 'jQuery': object is null or undefined


IE says that window.kendo is undefined in one of the window.kendo.jQuery statements.  Is this an environmental issue or is there something wrong with the actual files in this build?  Maybe it has something to do with the way new projects are initialized with VS Update 3.  I messed around with trying to host Kendo in a different MVC 4 project that was created as a standard project, instead of a Kendo project, but I get the same error.  Also, when I tried to bundle the scripts, instead of directly linking them, WebGrease gives an error.  Please, help.
