I created MVC 3 web application and then convert it to Kendo UI for ASP.NET MVC application. Plz see attached project.

There is a simple grid on index page, add new item button is on grid toolbar, edit and destroy buttons are in column.

I could add new row successfully, but when I try to edit existing row, another create action is posted again. Refresh page, two rows in grid. the same thing happens when I try to delete a row.

Why? Am I missing anything there?

Please advise.

hello all, 
i need to work on new project and we are planning to have rich data grid functionality. i searched for telerik controls for Data Grid and came to this Kendo UI . our platform would be Asp.net Mvc4. please help.

I have a panelbar in which the content is loaded via ajax.

I would like to reload the content based on the change event in a dropdown list.  However, it doesn't appear that I can do this.

I tried the reload() method on the panelbar object but it didn't do anything so I figured there was some caching involved.

Can I trigger a reload to occur?

Below is my client-side code and the panelbar.

thanks

Im trying to use the Kendo Grid for a minor project, where i want to show the column summary in the groupheader. But I cant get it to Work :-(. When i use the Groupfooter, then it works fine.

Anyone got any suggestions?

************************************************************************************
@(Html.Kendo().Grid((IEnumerable<FTEReport>)ViewBag.Test) 
     .Name("grid")
     .Columns(columns =>
{
 columns.Bound(FTEReport => FTEReport.Jan)
.ClientGroupHeaderTemplate("#=sum#");

columns.Bound(FTEReport => FTEReport.Feb)
.ClientGroupFooterTemplate("#=sum#"); 
}
 .DataSource(ds => ds.Ajax()
.Aggregates(aggregates =>
{
aggregates.Add(p => p.Jan).Sum();
aggregates.Add(p => p.Feb).Sum();
 })
.Group(g =>
{
g.Add(c => c.Allocated);
g.Add(c => c.Project);
g.Add(c => c.Department);
})
.Read(read => read.Action("Aggregates_Read", "grid"))
 )
)

I use a splitter with a left and a right pane within a window widget. If I create the window with “Visible(true)” everything works as it should.
But since the window is supposed to be displayed, when the user clicks on a button, I have to use “Visible(false)” and make it visible after the click occurred.
 In this case the given pane size of the left pane seems to be ignored and the right pane is not displayed at all(see attached picture).

After manual resize of the splitter, it seems to work. But when I close the window and reopen it via Javascript, the size parameter is still ignored. Instead the
manual chosen size is used. It makes no difference if I use Ajax Loading or direct rendering. My Code:

Window:
Splitter:
Button:

Am I missing something here?

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
