Dear KendoUI Team!
In one of my Views I alwas get a javascript error when I leave the focus of the Dropdownlist.

The error occurs in parseJSON in this line:
{return e.JSON&&e.JSON.parse?e.JSON.parse(n):null===n?n:"string"==typeof n&&(n=b.trim(n),n&&k.test(n.replace(S,"@").replace(A,"]").replace(E,"")))?Function("return "+n)():(b.error("Invalid JSON: "+n),t)}

The Model looks like this:
[Required]
        [LocalizedDisplayName("Language")]
        public int PreferredLanguageId { get; set; }

And the cshtml is here:

div class="type-text">                            
                            @(Html.Kendo().DropDownListFor(m => m.PreferredLanguageId)
                            .Name("PreferredLanguageId")
                            .SelectedIndex(Model.PreferredLanguageId)
                            .BindTo(LeoHelper.GetLanguages())
                            .DataTextField("Text")
                            .DataValueField("Value")
                            )
                        </div>

Although the javascript Exception is thrown, the value is correctly saved.

Hello,

I have an editable grid and added a filter dropdown on the toolbar

       .ToolBar(c=>
        {
            c.Template(Html.Kendo().DropDownList()
               .Name("tb_factory_list")
               .DataTextField("factoryname")
               .DataValueField("factoryid")
               .Events(e => e.Change("onChange"))
               .SelectedIndex(0)
               .DataSource(source =>
                   {
                       source.Read(read =>
                           {
                               read.Action("GetFactories", "Home");
                           });
                   })
               .HtmlAttributes(new { style = "width:300px;float:right" })
               .ToHtmlString());
        })


problems :

1) How do I get the 'add new item' button back  ?
.ToolBar(tb => { tb.Create();  })

2) the width of the dropdown is whatever the width of the initial displayed item.
I had to manually force the dropdown to be wider to accomodate the widest item in the dropdown (see above 300px)
Is that normal ? can the dropdown resize to the widest item in the dropdown ?

3) when the page is opened, the dropdown displays the first item, but the onchange event is not called.
So initially, the results are not filtered by whatever the dropdown shows.
after I select another item in the dropdown, then the onchange is fired and filtering happens.
How can I filter correctly when the page is first loaded ?

Thanks
Marcel

Questions in the image in attachemnt since I get a "invalid post content" message.

Hello,

I am using Kendo 2013.1.514.340 with asp.net mvc.

I am sending the Json to the grid that is generated from the following data structure:
I have two entities, Parent and Child.  A Parent can have n Children.  In this case a single Parent has two Children.  

I use NewtonSoft to serialize the Json with the following settings:

When I have the case of a single parent with a single child all works fine.

The following Json is generated for a single parent that has two children:



This leads to the following error:
I would really appreciate any about this issue!

Best regards

Hi

I have been look at Kendo a few days and now trying to move into to a Production alike environment (Testing).

When i start moving into the server (using Web Deploy), and browse to the page with the Kendo control. It dont render right.ex. for a grid It only show the table and text, but all the functionality is gone. I also try with a DatePicker here it only show a whitebox with text?  Looks like im missing some scripts files???

Consider the following cshtml file.  I have changed the style for the tab to hide the tabstrip item headers and added previous/next buttons to the page to simulate a wizard.  If I don't turn off animation for the tabstrip and the user double clicks on the previous or next button the contents of two tabs will be shown stacked on top of one another.  Is there anything I can do about this or is this a bug?

I have a column chart which does not show the legend even though I have set legend.Visible to true. If I uncomment the .Group line commented in the code below, then the legend starts showing, but unfortunately it displays the default colors rather than those I have customised with m => m.UiColor  
Sorry I am getting "Invalid post content." when trying to paste the code in this post so I have attached it as an image.

I have tried numerous solutions I have found googling this, but was unable to find anything that worked for me.
Basically, I have a grid that uses inline editing (with a few foreign key columns), and I need to set some fields as editable based on the value in another field. I have attached a screen print of the grid..
I would like the last column to always be editable, but the other columns should only be editable when the last column is not = 'LOGGED'.

The following is the definition of my partial view that contains the grid - using jQuery dialog to display as popup  ..

Hi,

I have a simple page with a droplist and a chart.  When selecting an item of the droplist, I update the chart with new values.  The new chart can have different number of categories.  On initial load the chart displays correctly with all the categories legend.  When selecting a different element from the droplist, the chart updates correctly but the categories legend does not.

For example, if the original chart had 5 categories and the selected item has 4, the chart still shows 5 categories where the 5th category is empty (no graph) but the 5th category legend still shows.  Whereas if the selected category has more series then the original, the chart displays correctly the additional categories but the the category legend is blank.  Somehow the category legend does not change. 

Using kendo version 2013.1.514.
Thanks,
