Hi
I see this your example for custom editing, now, I want to use this feature with Treeview.
I means that when a cell is in editing mode, show Treeview instead dropdown, and when user click on one of item, see this on that cell.
Is there possible?
can I see a example ?

Thanks for replay.

Result from Controller?

This is what I am returning as ActionResult from the Controller:

// oCats is List of Category objects so derives from IEnumerable

           var vResult = oCats.ToDataSourceResult(request);
           var x = Json(vResult, JsonRequestBehavior.AllowGet);
           return (x);

When I mouse over the breakpoint on the last line, I have all forty Categories properly . . . but when the View tries to load I get this:

"Unhandled exception at line 190, column 1 in Function code
0x800a138f - Microsoft JScript runtime error: Unable to get value of the property '__count': object is null or undefined"

in the Function js file and it crashes. Ideas for solution?

Thanks

[Solved] No marker lines on slider

I have a slider in our site, I am sure it had marker lines when I first put it in, but now it doesn't, I thought there must be some css overriding it, but removing all the css and still no marker lines,
what could be causing this? is there some css I should look at?
Any ideas I have spent a lot of time on this.
Thanks

Hi,
Just wonder if there may be any issues when we use a non-html5 MVC control (i.e. namely Spread.net) with the Kendo UI?

Trouble with Checkboxes

Hi,

Both Template and CheckboxTemplate do not seem to affect my nodes that have been created through BindTo. Special characters in the templates are also resulting in their escaped source code representations such as "\u0027". Can you guys please provide some advice and perhaps an example of a databound TreeView created through the Fluent API that uses checkboxes? Thanks.

[Solved] Grid won't render

I'm new to Kendo UI and MVC and am working on an ASP.Net MVC3 project using Razor. I've based my grid on a demo at http://docs.kendoui.com/documentation/getting-started/using-kendo-with/aspnet-mvc/helpers/grid/ajax-binding. I could easily do this as a traditional ASP.Net project in which I'm expert but want to master this new pattern.

My problem is that the grid won't render. The JSON content coming back appears valid to me. I've got a similar grid in DataTables where I've got the grid to at least render the first level but this one is proving to be stubborn. I'd prefer to use KendoUI if possible.

I've determined the the Ajax call is working and that JSON content is being returned to the browser. I'm not sure what might be wrong. I'm binding to a List collection of Batch objects. A Batch object has properties to be displayed in the first level of the grid. The Batch object also has a property that returns a List collection of Transaction objects which will be displayed on demand in the nested grid which I haven't gotten to yet.

Can anyone point me to where I've gone wrong? I've no clue what to do next and can't find any articles that look like a solution.

Here's the code I have so far:

// the controller

// called by Index2: returns a list of BatchHeader objects directly from the ROAMHostSvc

public ActionResult FetchBatchList2()

{

DateTime aDate = new DateTime(0001, 1, 1);

ROAMHostSvc.Notification messages1 = null;

ROAMHostSvc.ROAMHostSvcClient hostSvc = null;

KUI_CS_Test1.ROAMHostSvc.BatchHeader[] batchArr;

//List<KUI_CS_Test1.ROAMHostSvc.BatchHeader> batchCollection = new List<BatchHeader>();

try

{

hostSvc = new ROAMHostSvc.ROAMHostSvcClient();

batchArr = hostSvc.GetBatchCollection(ref messages1, false, aDate, aDate, false, aDate, aDate);

// assign the objects in the array to the List collection

//for (int i = 0; i <= batchArr.Length - 1; i++)

//{

// batchCollection.Add(batchArr[i]);

//}

//return View(batchCollection);

//return PartialView(batchCollection);

//return PartialView(Json(batchCollection, JsonRequestBehavior.AllowGet));

return Json(batchArr, JsonRequestBehavior.AllowGet);

}

catch (Exception ex)

{

return null;

}

finally

{

Close_WCF_Service(ref hostSvc);

}

private void Close_WCF_Service(ref ROAMHostSvc.ROAMHostSvcClient hostSvc)

{

try

{

if ((hostSvc != null))

{

if (hostSvc.State == System.ServiceModel.CommunicationState.Opened)

{

hostSvc.Close();

hostSvc = null;

}

catch (Exception ex)

{

throw;

}

//the view

@model KUI_CS_Test1.ROAMHostSvc.BatchHeader[]

@{

ViewBag.Title = "Index1";

}

<h2>Index1</h2>

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

.Name("batchGrid")

.Columns(columns =>

{

columns.Bound(b => b.BatchID);

columns.Bound(b => b.Transmitted_DateTime);

columns.Bound(b => b.Completed_DateTime);

columns.Bound(b => b.Created_DTTM);

columns.Bound(b => b.Created_EmpID);

}

)

.DataSource(dataSource => dataSource

.Ajax()

.Read(read => read.Action("FetchBatchList2", "Home"))

)

ComboBox retains value but not text on return to page

I created a couple of ComboBoxes and notice a strange thing if I do the following:

1. Select an item.
2. Navigate away from the page.
3. Use the browser's Back button to return to the page.

Upon returning, the ComboBox is blank (or the placeholder appears if I configured that). However, when I open the ComboBox, the item I had originally selected is highlighted. Thus, it appears that the value was retained though the text was not.

Is there any way to make sure the text retains its value on returning to the page?

(Note: I tried the same thing with a normal HTML select drop-down list, and the selected item remains selected upon return as expected.)

Thanks,

Ken

Dropdownlist in text column.

Hello all.
I'm wondering if someone can help me.
I have a MVC Kendo grid, that has AJAX binding. Within the grid, I have some TEXT coulmns. So on edit, it is a plain editbox.
But for some rows, I want the template to be a dropdown or a combobox.
I need this, because I want the user to select a restriced choise list.

I have varios reasonsfor this. But overall what I need is have a dropdown/combox on edit template on a TEXT based column of a data grid.

My current code looks like this:

--cshtml---

@(Html.Kendo()

.Grid<Shell.UI.UGOBooks.Models.GetAcreageData_Result>()

.Name("AcreageGrid")

.HtmlAttributes(new { style="height: 650px" })

.Columns(columns =>

{

columns.Bound(a => a.DataFieldText);

columns.Bound(a => a.UOMText)

.HeaderHtmlAttributes(new { style="text-align:center" })

.HtmlAttributes(new { style="text-align:center" })

.Width(100);

columns.Bound(a => a.DataFieldValue)
