Hello,

I have line charts with multiple data (even more than 10.000 points). I see that Kendo UI supports pan and zoom option. Though I found only example code for Html http://demos.kendoui.com/dataviz/bar-charts/pan-and-zoom.html. Is there some kind of example code for MVC ?


Best regards.

I have the Required attribute on my model, but when I use DatePickerFor, Kendo Validator does not pick that up.  If I use the F12 tools and manually add "required='required'" to the input that the DatePicker renders, then Validator picks it up and shows a message next to the picker.  Besides that, it's also not picking up the ErrorMessage on my Required attribute.  I'm assuming I could add another attribute to the <input> for it to pick that up as well, but not yet sure what the attribute name is.  Can you please explain why I can't just get this behavior out of the box, and if this is a bug with the DatePickerFor?  I'd rather not have to use .HtmlAttributes to manually stick these things onto every DatePicker.  Maybe I'm just missing something, but for something like this, you expect it to just work.  Thanks!

Hi there,

in my case, I have a ViewModel on the client side. It works and shows the data from the "real" model. The real model consists of an object that contains other objects, e.g. ArchivedDoubleValue refers to a Station, which has a name, via its StationId. In my ViewModel, things are flattened in order to be fast and avoid circular dependencies, so there is:

int Id (ArchivedDoubleValue.Id)
double Value (ArchivedDoubleValue.Value)
string StationName (refers to Station.Name and gets set in the controller)

Now, when I want to sort or filter the StationName column, I run into an error, because StationName does not exist in the "real" model, only StationId.

So I thought I could simply "translate" the Member String in DataSourceRequest.Groups and DataSourceRequest.Sorts back into the corresponding Id. That worked quite well:

When grouping in the client, the request.Groups contains an entry with its Member set to "StationName". This is just a string and I change it to the corresponding StationId. Same works well for sorting.

But it DOES NOT work for filtering!  When debugging and peeking into he request at runtime, I can see and change the Filters Members and Values, but when I try to change it via code in the controller, I can not access it:

            if (request.Filters.Count > 0)
            {
                foreach (var f in request.Filters)
                {
                    String fs = f.Member.ToString();

This gives me an error:
Kendo.Mvc.IFilterDescriptor does not contain a definition for "Member"

How am I supposed to filter the "real" data with the filter set to a column in my ViewModel? I wonder how to do that? Or is there a way to access request.Filters? I think that would be the most elegant way to do it as it wiould be transparent to the client.

Please help me with that, thanks in advance!

My Kendo Comboxbox server binding is not working

This is my View
 @(Html.Kendo().ComboBox()
              .Name("cbxState")
              .HtmlAttributes(new { style = "width:150px" })
              .Text("Select State")
     
              .DataTextField("Code")
              .DataValueField("Code")
               .Filter(FilterType.Contains)
              .DataSource(source =>
              {
                  source.Read(read =>
                  {
                      read.Action("cbx_read", "Home");
                  })
                  .ServerFiltering(true);
              })
              )


This is my Controller       

public ActionResult cbx_read([DataSourceRequest]DataSourceRequest request)
         {
             using (var northwind = new Connection())
             {
                 IQueryable<LostDayDetail> Customers = northwind.LostDayDetail;
                 DataSourceResult result = Customers.ToDataSourceResult(request, Customer => new CustomerDetail
                 {
                     Code = Customer.Code,
                     Name = Customer.Name,
                     Days = Customer.Days
                 });
                 return Json(result);
             }
        }

When I click on Combobox, it calls cbx_read function and it gets all 12 rows of data from database table. but when contol comes back to view, the combobox is blank.
Please help me

I'm sure this is actually really simple and I'm just making it really complicated, but I could really use a fresh set of eyes on this one.

When a user loads my page with the grid on it, I get the url referrer via JavaScript and analyze it via regex. If the url has a TransactionID (int) in it, I assign it to a JavaScript variable.

Here's my problem: I want to find the row in the grid with that TransactionID and have the grid go right to it (like if it's farther down the grid, I want the grid to scroll down to that row automatically). One way I think I can do this is to focus the row itself, but I can't figure out how to get to it in JavaScript. If I could find the row with the TransactionID, then just call the focus() function, I think that will solve this thing.

Here's what I have. Please help! :(

I need to make a cascading combobox with server filtering but I'm having trouble setting the initial value.The dropdownlist on which the combobox depends looks like this:

Where:

• model.SelectedCompany is a string
• Name attribute is set because I need that in the combobox (I've read on the Kendo UI forums I'm not supposed to specify it, but I don't know how to do the cascading combobox without it)
• Model.CompanyList is a List<string>

Hello,

I am using a Kendo Grid popup which displays a Kendo editor to modify the content of the field. The field is configured on the MVC server side with the annotation to validate length to be 500 characters as follows:

[AllowHtml]
[StringLength(500, ErrorMessageResourceName = "ActionMaxLength", ErrorMessageResourceType = typeof(Resources.Messages))]
public string Action { get; set; }

If the user enters more than 500 characters in the Kendo editor this validation works. However, our users reported that when they added more formatting (tables, bullet lists) the validation pops up even if the visible character count is not 500. I understand from a technical perspective the character count being validated includes the behind-the-scenes html formatting tags, however this is not intuitive to the end user.

My question is, is there any alternative or built in approach to validate just the html-stripped character count of the Kendo editor validation?

I am currently trying to add custom markers to a map in MVC C#.
Is there anyway of creating a different shape/image in MapMarkersShape to display it on the map?
My current code is as follows:

@(Html.Kendo().Map()
    .Name("map")
    .Center(30.268107, -97.744821)
    .Zoom(3)
    .Layers(layers =>
    {
        layers.Add()
            .Type(MapLayerType.Bing)
            .Shape(MapMarkersShape.Pin) // -< this line
            .Key("XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX"); 
    })
)

Thanks

I have a View with multiple dropdowns(15-20). Currently I implemented server binding for all of these by creating ViewData for every dropdown before loading the View. Is this the best way for implementing multiple dropdowns(server binding)?
Note: Don't want to use AJAX binding.

Hi,
 
I have used Kendo UI in an MVC web application. Of late I have been experiencing slowness in IE8 browser.
While the same code loads the screen in less than 2 secs in Chrome/IE10, it takes more than 5-6 seconds to load in IE8 browser.
Kendo widgets used in the screen includes Dropdowns, Treeview and Kendo Tabstrip.
I have tried replacing the kendo dropdowns with normal ones. This gave me a slight improvement of about 1 sec.
The kendo dropdown is a part of my cshtml page and not initialized by the jquery. Is this the best way to implement kendo widgets?
Is there any other way which will provide me with a better performance?
