I'm having problems to add/edit/delete rows on a grid loaded from DataTable

I have something like the following code:
In the above code if I uncomment the "commented lines" .. the exception is:

"Templates can be used only with field access, property access, single-dimension array index, or single-parameter custom indexer expressions." 

Could you tell me what I should do to enable CRUD operations on this case?

Thanks

Is it possible to have only create and destroy button BUT NO EDIT button shown in a grid?

I have tried not to include edit command but on addition, the update and cancel buttons are not shown.

regards

Hi!
I have problem with client-side validation.  Even after I set Culture and it shows proper date format, when I submit page client-side validation fires error "The field Datum očitavanja must be a date.". Here is my code in view:

Please for some instruction. Thanks!

Hello,

I need some help to complete below functionality.

I am trying to bind/create a template column, so when the grid loads it can call an html helper or controller action to get the value/text for that column. Which means, i am trying to bind a non modal or datasource property  to one of the grid columns.

Goal: Bind one of the columns in kendo grid with external text.

My grid looks something like this,

 @(Html.Kendo().Grid<Model>()
          .Name("Grid")
          .AutoBind(false)
          .Columns(columns =>
              {
                  columns.Bound(row => row.Id).Hidden(true);
                  columns.Bound(row => row.Name);

                 columns.Template(@<text>@Html.GetSomeText("SomeContext")</text>).Title("title");

                 columns.Template(@<text>@Html.Action("GetSomeText", "controller", new {ctx = SomeContext})</text>);
               }

As you can see above, I tried couple of ways to get the text for the column - Html helper and Action Method, but in both the cases, server side code is not even being triggerd and column remains empty in the grid.

Any help is much appreciated.

Thanks,
Balwant

Hi, 

during evaluation of the KEndo library, I am now facing the next problem which I spent a lot time with now...

I try to create a listview. My viewmodel contains references to other classes, let's say I have a model class Person, which contains a property Address of type Address, which again has properties "Street" and "City".

So, I defined my template like this (also my editor template):

<script type="text/x-kendo-tmpl" id="template">
     <div>
       <dl>
         <dt>Street</dt> <dd>${Address.Street}</dd>
         <dt>City</dt> <dd>${Address.City}</dd>
       </dl>
     </div>
 </script>

But this leads to JavaScript exceptions, saying that the property is undefined. How can I handle this? Any idea is welcome, but this really a serious problem with complex data models. I cannot reduce my viewmodel to only have primitive properties, that woud cause too much effort...

Thanks!

I have an ASP MVC 4, .Net 4.5 project.  I am using the new EmailAddressAttribute validation data annotation attribute on my view models to validate a correct email format is posted.

The attribute is correctly rendered on the input element as <input type="text" ... data-val-email="Email address format is incorrect" .../>.

If I use the kendo validator to validate my form before post to server, the email rule seems to be ignored.  I believe I have included all the necessary js files to support unobstrusive validation.  All my other data annotation rules are applied correctly.

When I look at kendo.aspnetmvc.min.js, it appears as though the kendo "email" rule is never mapped to the data-val-email rule pattern?

If I write my input element from scratch <input type="email" required .../> obviously my email rule is applied correctly by the kendo validator.  This is not an ideal solution though because I am trying to standardise on using the data annotation attributes for my view models.

Can you please tell me if I have done something wrong?  I rechecked the 2012 q3 beta and it appears to have the same limitation.

Thanks

Maybe I'm going about this the wrong way but the model populating the AutoComplete has an Id and a Name.  I display the Name but when the form is submitted I need to return the Id since it will bind to the property on the model.

Presently the AutoComplete is populated correctly when I start entering data, but when I submit the form, the widget has the red border meaning that it's not returning the int property type but the string type.

These are two of the AutoComplete properties on my model that I need to bind to:
Here is my Vendor AutoComplete widget:
Bottom line: I need to bind the Id of the selected value back to the controller, so I need to know how to return the Id from the AutoComplete widget and include it with the response.

Any help on this is appreciated.

Thanks.

I have a Db table that has a SiteKey, SiteValue, Description columns. No Id's.
For example,
SiteKey    SiteValue
ACode     ABC
BCode     XYZ
CCode    123
I want to display this in a View
--------------------------
A Code: ABC
B Code: XYZ
C Code: 123
---------------------------
| EDIT |
----------------------------
And a Button to Edit. On click, make the display boxes for values to Inline Editing with the option to Save or Cancel.
Can you show me a sample to do this with Kendo? I am able to do this as a separate Edit View but want to use kendo widgets if possible. Since the data is unrelated, not sure what to use or if this is possible.

Hi everyone,

I'm a database engineer new to the ASP.NET MVC world, and recently purchased the Telerik Kendo UI tool kit for ASP.NET MVC in order to transition away from Silverlight. While I appreciate the thoroughness of the examples provided by Telerik, what I would have preferred is individual projects for the various tools. I'm sure those accustomed to working with MVC in general are able to cut through all the chaff and get to what they need, but all I really want is to understand how to use a basic grid for now; I'll build on that understanding later. A project/solution with just a basic grid implementation would save me a lot of time.

Does anyone know if there is a project repository on Telerik or KendoUI.com that would suit my needs? I've looked through the forums, but figured I'd start asking here before submitting a support ticket.

Thanks in advance for any help for this novice!
