Hi here,

I'm building a web application with ASP.NET MVC4 and everything runs quite well so far. No I wanted to integrate Kendo UI to my _Layout.cshtml file in order to use some widgets. So I followed these steps (here) to include the neccessary scripts and styles, but when I run the project, it throws a JavaScript exception:

Unbehandelte Ausnahme in Zeile 17, Spalte 14133 in http://localhost:54430/Scripts/KendoUI/js/kendo.all.min.js
0x800a138f - Laufzeitfehler in JavaScript: Die Eigenschaft "msie" eines undefinierten oder Nullverweises kann nicht abgerufen werden.

When I comment out the reference to kendo.all.min.js everything works flawlessly. What can I do? I'm having a hard time telling my Boss that it actually was a good idea to spend more than thousand bucks on a bunch of tools that do not work. Please help me wih that!

Regards,
Rob

Here's my code:

(PS: I also tried adding a reference to kendo.aspnetmvc.min.js (one time before Kendo.all.min.js, another time behind it), but it didn't help.)

Error 5 'System.Web.Mvc.HtmlHelper<System.Collections.Generic.List<SOH.Common.Model.Patient>>' does not contain a definition for 'Kendo' and no extension method 'Kendo' accepting a first argument of type 'System.Web.Mvc.HtmlHelper<System.Collections.Generic.List<SOH.Common.Model.Patient>>' could be found (are you missing a using directive or an assembly reference?) c:\VSProjects\SOH.Orthodontics\SOH.Orthodontics.Web.UI\Views\Patient\PatientResult.cshtml 5 8 SOH.Orthodontics.Web.UI

Really struggling with this error.  Please help!  Html.Kendo() in the razor view just is not recognised!  Argh!!

Added a reference to the dll and also added namespace to BOTH web.config files.  Sections below from both files.

I have an ajax grid with several pages of data that I allow users to perform CRUD operations on using the InCell edit mode. However, if I change pages or ordering or manipulate the page in any way after making a change the default behavior is to discard changes. I've noticed that if I set .ServerOperations(false), I can navigate without losing my changes but I also lose the 'dirty mark' indicating that there have been changes. This is likely to cause users to navigate away from the page and lose those changes with no feedback from the page. While that can still happen with a dirty mark, the client has decided that they would prefer that any changes be saved prior to changing pages or filtering (basically, any of the _Read events).

What is the best way to enable a save operation prior to losing data in such a grid? 

Hi,

I have to say, I wasted now really a lot of time in figuring out how the css styles are applied to the grid edit controls:

I did two tests:
1) Use the Kendo Grid with Javascript configuration
2) Use the grid with MVC Wrapper configuration

And I get different styles for the editors (e.g string editors) when doing that! After research, probably that's what explained here: 
http://docs.kendoui.com/getting-started/using-kendo-with/aspnet-mvc/helpers/grid/editor-templates

In Version 1), the text boxes get the class "k.input k-textbox". Fine, that's what I want
In Version 2), the tet boxes get the class "text-box single-line". Why the difference?

Do I really have to declare editor templates now for every data type I want to edit? In that case, I could probably go on with the free Kendo edition and do not use the server wrappers. Why does it cause additional effort when I use them? Can someone explain?

Thanks!

Is it possible to have forced list matching similar to the ComboBox in the non-Kendo controls (http://demos.telerik.com/aspnet-mvc/razor/combobox/clientsidebinding) in the Kendo ComboBox? It seems there is no way to prevent the user from typing whatever they like into the input box.

This functionality also exists in the ASP.NET Ajax Combobox (http://demos.telerik.com/aspnet-ajax/combobox/examples/functionality/autocompleteclientside/defaultcs.aspx)

Problem 1:
I can't seem to get a grid in a Editor Template to work in a popup editor window of a grid.  I have attached a sample of this issue.  If you select the Grid Editor Menu Item you will see that it crashes.  If you remove the Html.Partial statement from the TopLevelItem Editor, you will see that it works.  To demostrate that the template works fine, I added a Direct Edit Menu ITem that calls the Template which led me to my second problem....

Problem 2:
If you use the Direct Edit menu item at first glance everything looks ok.  If you pay close attention to the dropdown for ItemType (not the one in the grid, that is itemtype2 and works fine), it doesn't select the correct default value.  Upon forther inspection, it doesn't seem to behave in the same manner as when inside the Grid Popup editor.  If you post it back, only the ID is trying to be return (inspect the Request object's Forms collection) but not the entire model.  The Item Type is null.  Again, this works fine inside a Grid Popup.

My intial thought was to host the editor in my own window using custom actions on the grid, but then I ran into problem 2.

Any thoughts on this?  Is this a bug?  Unintended use?

i 've used kendodropdownlist to asp.net page having master page but it's not working .
but same dropdownlist working on without master page.
please help me out .

Hi,

We are facing an issue with an editor template  being used in a grid column. The editor template is supposed to show the phases of treatment of a patient in an application which we are building.

The first time when the page loads, the grid shows correctly with patent id in the first column and the editor template showing 'pre - treatment' in the second column (as a dropdown list).

However, when we try to add a new row to the grid with a button click, in addition to a new row being added, it is observed that in the initial row as described above, the editor template changes from dropdown list to textbox, with the value (pre - treatment) being lost.

We are attaching a code sample for your kind reference.

I have a minimal grid embedded in an .ascx file, which is embedded in a .aspx file.



Clicking on the 'add record', 'save', or 'cancel', causes the page to scroll to top, and the correct action is never taken. This code work in a minimal setup in a new project. The problem is this is a legacy project, and I need to figure out why I can't get the grid to work in this existing page.

The javascript console does not show any errors, even when the buttons are clicked. There seems to be no indication of why it isn't working.

EDIT: I attached attached to the click event breakpoint in chrome, and in my minimal example that works, the first handler for the click of the button is the jQuery click handler which then dispatches to a kendo handler. On my project that doesn't work, the jQuery handler is never called. Yet I recieve no errors about jQuery missing, and indeed the kendo grid renders and sorts fine (which I thought it would not do without jQuery. I am using the jQuery  1.8.3.

Thanks,

Hi,

This must be something already discussed, but I couldn't find a solution.

We need to implement a Reset button on the view with KendoGrid, which needs to clear/empty the grid (datasource). It's only clearing the UI element, but not deleting the record.

Tried jquery empty(), but doesn't look like its supported. That may be the option to use, but couldn't find any so far...

$("#gridId").data("kendoGrid").dataSource.empty();

Want to see if anyone had such scenario and have had any luck implementing the functionality?

Input on any appropriate approach is much appreciated.

Thanks,
Balwant
