Hi ,

I am trying to set the Tool tip for Kendo Create button on the grid toolbar.

Can any one help me in setting it up on writer grid and agent grid.

This is how I am setting up the Add new record button in toolbar. --> { name: "create", text: "" }, in the demo below.

Thanks

I have a Kendo UI MVC control on my asp.net MVC page, i want to highlight specific dates based on information from my database. EG on 9/Aug/2012 there were 7 appointments raised.


I'd like to use the custom template like this 


    <%= Html.Kendo().Calendar()
            .Name("calendar")
            .Value(DateTime.Today)
            .HtmlAttributes(new { style = "width:330px" })
            .Footer("Today - #=kendo.toString(data, 'd') #")
                .MonthTemplate("# if ($.inArray(+data.date, events) != -1) { #" +
                                "'<div class=\"" +
                                "# if (data.value < 10) { #" +
                                        "exhibition" +
                                    "# } else if ( data.value < 20 ) { #" +
                                        "party" +
                                    "# } else { #" +
                                        "cocktail" +
                                    "# } #" +
                                "\"></div>" +
                            "# } #" +
                            "#= data.value #")                     
    %>
    
    <script>
        var today = new Date(),
            events = [
                +new Date(today.getFullYear(), today.getMonth(), 8),
                +new Date(today.getFullYear(), today.getMonth(), 12),
                +new Date(today.getFullYear(), today.getMonth(), 24),
                +new Date(today.getFullYear(), today.getMonth() + 1, 6),
                +new Date(today.getFullYear(), today.getMonth() + 1, 7),
                +new Date(today.getFullYear(), today.getMonth() + 1, 25),
                +new Date(today.getFullYear(), today.getMonth() + 1, 27),
                +new Date(today.getFullYear(), today.getMonth() - 1, 3),
                +new Date(today.getFullYear(), today.getMonth() - 1, 5),
                +new Date(today.getFullYear(), today.getMonth() - 2, 22),
                +new Date(today.getFullYear(), today.getMonth() - 2, 27)
            ];
    </script>


How can I replace the above javascript array with an array on my viewmodel?
Something like this - 


    .MonthTemplate("# if ($.inArray(+data.date, " + Model.Array + ") != -1) { #" +
                                    "'<div class=\"" +
                                    "# if (data.value < 10) { #" +
                                            "exhibition" +
                                        "# } else if ( data.value < 20 ) { #" +
                                            "party" +
                                        "# } else { #" +
                                            "cocktail" +
                                        "# } #" +
                                    "\"></div>" +
                                "# } #" +
                                "#= data.value #")                     
        %>


Thanks

Hello,

I am trying to make this grid using Json. The filters for Country code and Company codes are not working. I have attached the screenshot of the grid (grid value is not provided for security of data). As you can understand form the code snippet that "userConstraints" field is an object which later split into two columns Country Code and Company Code and where the filters are not working. I would like to make it work in client side. Do not prefer to solve it in sever side. Please let me know if i missed anything. Thanks in advance!

Screen Shot:


Json Data for Field "userConstraints"


Code Snippet:
getUsers: function (data, response) {

Hi guys, I'm new to Kendo and am struggling to understand why the change and error event handlers defined in my datasource are not called. I have a grid with popup edit functionality. I would like to display a notification when a record has create, update or delete operations performed on it. Any advice is appreciated.

Hello
For a project I have a strong requirement to manage authenticated users either using a CAS (Central Authentication Service) or as a second option a LDAP authenitcation
Is it something available when developping witthin Kendo UI?

Something else I will need to implement, changing CSS styles on the fly. In other words to be able to download a new CSS style file and change it on the fly?

Should it be easy to develop an app with Kendo UI, managing several languages languages?

many thanks by advance

After releasing our first Kendo web app to the public we received a lot of feedback about the listview scrolling having a very bad performance. Some users on older smartphones weren't able to scroll down in an appropriate way at all.

So we decided to switch to native scrolling following this documentation: http://docs.telerik.com/kendo-ui/getting-started/mobile/native-scrolling

Instead of

new kendo.mobile.Application(document.body, { useNativeScrolling: true });

which completely screwed our whole app, we used data-use-native-scrolling="true" for the views.

After the change, scrolling was very performant, but we encountered a strange behaviour of the listviews regarding setting back the scroll position. We tried several ways of resetting the listviews scroll position:

1. via e.view.scroller inside the show() event

The documentation mentioned above states that there is no scroller object when using native scrolling, but in fact there is. So we used e.view.scroller.scrollTo(0, 0) at the end of the show() event.

Problems: several users reported that clicks on listview items were not correctly processed, instead a different listview items click event was executed, leading to the wrong details page.

2. via window.scrollTo(0,0) (as recommended in the documentation)

Problems: when going back using the phones back button, the listview jumps to the top before switching the view. Looks really awkward. Also, the listviews scrolling position is often not set back, it stays scrolled.

3. no scrollTo() at all

Problems: same as 2.


So I have 2 questions:

1. What would be the correct way to handle a view with a listview using native scrolling?

2. Is the abysmal scrolling performance with listviews normal? Even on the newest quad core devices we noticed a huge performance difference to native scrolling. Is there a way to optimize that?

Thanks in advance for any hint on this,
Roman

I have read how you can add a dependent method / calculated field to an ObservableObject (http://docs.kendoui.com/getting-started/framework/mvvm/observableobject), but I cannot find how you can define a dependent method / calculated field in the schema of a Model (http://docs.kendoui.com/api/framework/model). The instances of my Model are read from a remote kendo DataSource, so I need to define a dependent method / calculated field in the schema of the Model so that every instance of my Model automatically has this dependent method / calculated field. I've tried defining it as a field with the defaultValue set to the function and set nullable: true, but all the instances of my Model end up with null values in this field. Here's an example:


so when I get an instance of my Product from my kendo DataSource its CategorySortOrder property is null. So, how to define dependent method / calculated field in model schema?

I am sure this is a dumb question but I have not been succesful in finding the answer.  How do I get the value of a querystring example below im trying to get the querystring value from querystring parameter named ID and set it in the data part of my datasource.  my data source works hard coded.

var

 

 

dsDetails = new kendo.data.DataSource({

group: { field:

 

"_Title", dir: "asc" },

transport: {

read: {

url:

 

"../api/EventDetails",

dataType:

 

"json",

data: {

ID:

 

"4dc2fa9a-fb45-4ff5-b6d8-c246dbd3024e";

}

}

}

},

schema: {

model: {

fields: {

_ID: { type:

 

"string" },

_BeginDate: { type:

 

"string" },

_Cost: { type:

 

"string" },

_EndDate: { type:

 

"string" },

_EndTime: { type:

 

"string" },

_EventType: { type:

 

"string" },

_StartTime: { type:

 

"string" },

_SupportedBy: { type:

 

"string" },

_Title: { type:

 

"string" }

}

}

},

});

ds.read();
