Databound event doesn't fire

Hi,

I'm using a TreeView like in this example. It is located in the left pane of a two pane splitter, if that matters. All events fire as they should, except the DataBound one. I already tried to modify the example code, that comes with kendo. It does not work here, too.

My TreeView code:

@(Html.Kendo().TreeView()

.Name("MyTreeView")

.BindTo(Model, mappings => mappings.For<TreeViewNode>(binding => binding

.ItemDataBound((item, node) =>

{

item.Text = node.Name;

item.Id = node.Value.ToString();

item.Expanded = ViewData[ViewBag.ExpandedCookie] != null &&

((string[])ViewData[ViewBag.ExpandedCookie]).Contains(item.Id);

//item.HtmlAttributes["data-selectable"] = node.Selectable;

if (node.AddOnly)

item.HtmlAttributes["data-addOnly"] = true;

else

item.HtmlAttributes["data-addOnly"] = false;

if (!node.Selectable)

{

item.HtmlAttributes["style"] = "color: #888";

}

else

item.HtmlAttributes["style"] = "color: black";

})

.Children(parent => parent.Childs))).HtmlAttributes(new { @class = "k-group" }).Events(e => e

.Select("onSelect")

.Expand("updateTreeViewState")

.Collapse("updateTreeViewState")

.DragStart("onNodeDragStart")

.DataBound("onTreeDataBound")

.Drop("onNodeDrop")).DragAndDrop(true)

)

And the javascript code:

function onTreeDataBound(e) {

alert("databound");

}

// select event as an example (this works)

function onSelect(e) {

var dataItem = this.dataItem(e.node);

$("#ID").val(dataItem.id);

if ($(e.item).attr("data-selectable") == "0" || dataItem.id == "0")

e.preventDefault();

else

// request server for partial view for details and refresh right pane of splitter

getSplitter("#outerSplitter").ajaxRequest("#right-pane", "/" + getArea() + "/" + getController() + "/Details", { id: dataItem.id });

// update statusbar to default

$("#lblStatus").text("Ready");

$("#lblStatus").css('color', 'black', 'font-weight ', 'normal')

//}

}

Am I missing something here?

Best Regards

Dynamic columns in grid

Hi,

I just watched the keynote to the new release Q3/2013. While there are many cool features, I am a little underwhelmed by what was presented regarding adaptiveness of the grid.

What I expected: I thought there would be a feature that allows me to dynamically (depending on the screen size) add or remove columns shown in the grid. That's rather a usecase for me than soemone showing the grid on a mobile.

Are there solutions for this? I think there were announced at some point in time, not long ago...

Thanks,
Volker

Edit: Here is the link to the blog post I had in mind:

Connecting EF Data to Grid "circular reference" error

So I have a grid that is populated from EF5

@model IEnumerable<HCS.Model.FinancialInstitution>

@(Html.Kendo().Grid(Model)

.Name("Grid")

.Columns(columns =>

{

columns.Bound(p => p.ID).Visible(false);

columns.Bound(p => p.MainRT).Title("RT").Groupable(false);

columns.Bound(p => p.LegalName).Title("FI Name");

})

.Sortable()

.Scrollable()

.Filterable()

.Selectable()

.DataSource(dataSource => dataSource

.Ajax()

.ServerOperation(false))

)

I recently added a new table to the database that has a FK to the FinancialInstitution table
I updated the model and the association and navigation are now present.

However, now I get the following error:

"A circular reference was detected while serializing an object of type 'System.Data.Entity.DynamicProxies.FinancialInstitution_1..."

I have found a few articles suggesting the disabling of proxy creation, but this doesn't seem to help.

public ActionResult Grid()

{

context.Configuration.ProxyCreationEnabled = false;

var model = context.FinancialInstitutions.ToList();

return View();

}

I also found a blog that suggests a workaround however, I am confused as to whether or not I will have to do something every time a call is made to EF to rewire the JSON results

Issue binding/dispalying data in grid (using razor vs. javascript)

I have a grid that I am displaying and I am trying 2 different methods.... The jquery version works and displays the data in the grid...

In Fiddler, I can see the return JSON and everything looks as it should in the browser

var url = "/memo/a/8/b/1"; // build URL to API

var dataSource = new kendo.data.DataSource({ // create datasource
transport: {
read: {
url: url,
dataType: "json",
}
}
});

When I try the same call using Razor (my preferred way), this will not display any data in the grid. I see in Fiddler the exact same return JSON as as the Jquery method above. But no data is being displayed. Any suggestions?

@(Html.Kendo().Grid<eWJB.Models.MemoModel>()
.Name("grid1")
.Columns(columns =>
{
columns.Bound(p => p.MemoID);
   columns.Bound(p => p.Subject).Width(100).Title("Subject");
columns.Bound(p => p.Initials).Width(30).Title("Initials");

})
.DataSource(dataSource => dataSource
.Ajax()
   .Read(read => read.Url(Url.RouteUrl("GetAllMemos", new {httproute ="", controller="Memo", branch=1, id=8 })).Type(HttpVerbs.Get))
)
.Sortable()
.Scrollable()

)

A circular reference was detected while serializing an object of type - and I did not include the 'circular reference'

I'm at a lost. I've attempted to run my "Batch editing" grid with MVC3 and I keep receiving this error:
"A circular reference was detected while serializing an object of type 'System.Data.Entity.DynamicProxies.aspnet_Users_8928C46E971F379B4E2E99263A0AD4EE44DD31017D7C2242241BF00A73BA81B3'."

I've read other forums such as :

http://stackoverflow.com/questions/12845016/kendo-ui-invalidoperationexception-a-circular-reference-was-detected-while-se
http://docs.kendoui.com/getting-started/using-kendo-with/aspnet-mvc/helpers/grid/faq#how-do-i-avoid-circular-reference-exceptions?

I understand I can't reference a circular reference from my model in the controller or view, which I'm not and I keep receiving this error.

I'm also using Linq with the model first approach, but I do use a metadata model to add attributes to the models fields.
Here is some of my code.

Key cannot be null error on upgrade to the latest MVC wrappers

I just updated my solution to the latest release of Kendo and the MVC wrappers. Everything is working exactly as it did before except the tool tip which is now throwing the following error. Does anyone know why this has started and what the solution is? Included first is my code, and then the error thrown.

<div id="quick-menu">

</div>

Uploading files and checking for file tampering

I know this may be outside the scope of things here.

I have a telerik Ajax.net website that is used in a similar way to the likes of wetransfer.com

after a a recent pen test the security guys were able to get around the filters in place and spoof some files onto the server and gain remote access.

Obviously not a good thing. So the site has been taken off line,

I was looking to upgrade the site using kendo and was wondering if you had any advice on how I can try and prevent this sort of tampering or point me in the right direction to try and secure the site.

The site is a great idea for helping transfer large files to groups of people and getting past email restrictions so any ideas would be greatly received.
