Hi,
I'm using the grid with the popup editor. All is well but when I click the update button the grid doesn't call the update url given to my datasource. I have the latest 2012.1.322 version of kendo. Is there a specific configuration I need to give to my grid for this to work?!!

gridContainer

.kendoGrid({

dataSource : dataSource,

pageable : false,

height : 400,

sortable : true,

toolbar : [ "create" ],

columns : [

{

field : "firstName",

title : "First Name"

},

{

field : "lastName",

title : "Last Name"

},

{

field : "email",

title : "Email"

},

{

field : "status",

title : "Status",

editor : statusEditor

},

{

field : "telephone",

title : "Telephone"

},

{

field : "jobTitle",

title : "Job"

},

{

field : "newsSubscription",

title : "Subscribe to news?"

} ],

editable : "popup"

});

var grid = gridContainer.data("kendoGrid");

}

});

function createDataSource(readUrl, updateUrl, destroyUrl, createUrl){

return new kendo.data.DataSource({

transport : {

read : {

url : readUrl,

dataType : "json"

},

update : {

url : updateUrl,

dataType : "json"

},

destroy : {

url : destroyUrl,

dataType : "json"

},

create : {

url : createUrl,

dataType : "json"

},

parameterMap : function(options, operation) {

debugger;

if (operation !== "read" && options.models) {

return {

models : kendo.stringify(options.models)

};

}

},

batch : true,

pageSize : 30,

schema : {

model : {

id : "id",

fields : {

firstName : {

validation : {

required : true

}

},

lastName : {

validation : {

required : true

}

},

email : {

validation : {

required : true

}

},

telephone : {

validation : {

required : false

}

},

jobTitle : {

validation : {

required : false

}

},

newsSubscription : {

validation : {

required : false

},

type : "boolean"

},

status : {

validation : {

required : false

},

type : "text"

}

},

data : function(data) {

return data.users;

}

});

}

Thank you,
Valanto

Errors binding DataSource to WCF service

I have a WCF RESTful service (http://localhost:8000/AccountService/GetAccounts) outputting valid JSON data:

[
{"Department":"Manager","ID":"1","Name":"Alexandre Heuze","Position":"General Manager"},
{"Department":"Accouting","ID":"2","Name":"Pengli Liu","Position":"Accounting Manager"},
{"Department":"Human Resources","ID":"5","Name":"Jie Wu","Position":"HR Administrator"},
{"Department":"Sales and Purchasing","ID":"6","Name":"Fei He","Position":"Sales Manager"},
{"Department":"R and D Department","ID":"10","Name":"Jun Zuo","Position":"R and D Engineer"}
]

The following code does not bind the JSON output to the Grid Widget:

var wcfDS = new kendo.data.DataSource({
transport: {
read: {
url: "http://localhost:8000/AccountService/GetAccounts",
dataType: "json"
}
},
error: function(e) {
alert(e.toString());
}
});
$("#grid").kendoGrid({
dataSource: wcfDS,
columns: [...]
});

The most relevant error message I can see is e.errorThrown = "No Transport". Your thoughts?

Kendo.common.css Firefox Button Padding

We have a page where we have included the kendo.common.css stylesheet. When we view this page in Firefox, we notice that all of our buttons are really tall. We've tracked this issue down and it is due to the following style in kendo.common.css:

/* Override the important default line-height in Firefox 4+ */

:-moz-any(input[type="submit"], input[type="button"], input[type="reset"]) {

padding-bottom: 0.37em;

padding-top: 0.37em;

}

This applies top and bottom padding to any button on our page. This seems wrong, should this not be something more specific than any button, maybe something like (or some variation thereof):

/* Override the important default line-height in Firefox 4+ */

input.k-button:-moz-any(input[type="submit"], input[type="button"], input[type="reset"]) {

padding-bottom: 0.37em;

padding-top: 0.37em;

}

Thanks,
Sara

Grid calling function from template

This should be simple but it appears that the local function cannot be found from a template.
What's missing?

See http://jsfiddle.net/JVPa5/2/

...
template: '#= Simple(OffDuty,OnDuty); #'
...
function Simple(a,b){
return a + b * 100
}

Swipe to right on list view item

Hi,

In our application we need a swipe function in a listview, that behaves similarly to that of the iphone messages inbox. So when you swipe to the right (on a item in the listview) it shows a button that allows you to delete the item.

Please advise if there is such a feature available or if it will be available in the future? Otherwise would it be possible to implement our own using the html 5 touchstart and touchmove events? We've had issues trying to implement these side by side with kendo ui mobile...

Thanks

Remote view button error with phonegap and android

I've created a simple application with phonegap which consists in 2 html files (index.html and about.html)
Each of these files contains a single <div data-role="view">.
The index.html contains a button (<a href="about.html" data-role="button">)

If I put these files in a webserver they work correctly (the button when clicked navigates to the about.html page). However if I deploy these files through a phonegap application I get the following error message in LogCat (Android 2.2 emulator): TypeError: Result of expression 'd' [undefined] is not an object. at kendo.mobile.min.js:8

The sushi sample application suffered from the same error with it's "About" button when I deployed it through phonegap.

Is there a workaround this issue or any patch available?

Thanks

2 Bugs: Fractional percentage handling

Having dug around in the code, there appear to be two bugs in the kendo core relating to the handling of percentages.

Bug 1: Parsing percentages to floats
The first bug is fairly simple: percentages are mapped to a number between 0 and 1 for percentages 0% to 100%. The bug appears to be in the method kendo.parseFloat(value, culture). When the value is something like "12%" it correctly identifies it as a percentage here:

} else if (value.indexOf(percentSymbol) > -1) {

number = percent;

symbol = percentSymbol;

}

however, it subsequently just removes the percentage symbol but doesn't scale the value down by dividing by 100:

value = value.replace("-", "")

.replace(symbol, "")

.replace(nonBreakingSpaceRegExp, " ")

.split(number[","].replace(nonBreakingSpaceRegExp, " ")).join("")

.replace(number["."], ".");

value = parseFloat(value);

if (isNaN(value)) {

value = null;

} else if (negative) {

value *= -1;

}

return value;

This results in a value such as "12%" being changed to "1,200%" when using the percentage formatting such as:

kendo.toString(value, 'P')

Bug 2: Entering fractional percentages
The second problem I've found relates to using fractional percentage values. In my application I need to display percentages to 10dp and have therefore overridden the culture settings as such:

kendo.cultures["en-US"].numberFormat.percent.decimals = 10;

For reference, here's a stripped down version:

$("#grid").kendoGrid({

autoBind: false,

dataSource: {

schema: {

model: {

id: "Title",

fields: {

Title: { editable: false },

Percentage: { editable: true, type: "number" }

}

},

columns: [{

title: "TITLE",

field: "Title"

}, {

title: "PERCENTAGE",

field: "Percentage",

format: "{0:P}"

}],

editable: true,

scrollable: false

});

When providing the original model, a value such as 0.003425 is displayed as "0.3425000000%".
When clicking the cell to edit, the number editor simply displays "0".
If I then enter a fractional value such as "0.012345678912", the expected new value in the model should be "1.2345678912%" but is actually rounded to "1.0000000000%" and the value in the underlying model is saved as 0.01

Is there any way we can get more accurate values working in kendo or is there something else limiting us to 2 d.p. in the model?

Thanks in advance,

Daniel

ListView with selection and action buttons

I have a listview uses the selectable property as true, and in the item templateI have a link to remove an item.

But, when I click the link the change event fires first.

Is there a way to know in the change event that the remove was called?
