Load html content of an external file onto ScrollView

Hi,

Is there a way to load a content of an external file onto a ScrollView?

Suppose I have a file named data.html with the following content:

data.html
<b>
This is a sample text in data.html
</b>

Then I have a kendoUI page like this:

<!DOCTYPE html>
<html>
<head>
<title></title>

<link href="css/kendo.common.min.css" rel="stylesheet" type="text/css" />
<link href="css/kendo.default.min.css" rel="stylesheet" type="text/css" />
<link href="css/kendo.mobile.all.min.css" rel="stylesheet" type="text/css" />
<link href="css/TON/generic.css" rel="stylesheet" type="text/css" />

<script src="cordova-2.5.0.js"></script>
<script src="js/jquery.min.js"></script>
<script src="js/kendo.mobile.min.js"></script>
<script src="js/kendo.all.min.js"></script>
</head>

<body>

<div data-role="view" id="pregnancyarticledetails" data-layout="default" data-title="Shocker" data-init="mobileListViewDataBindInitFlat">

<div id="article_content">
<div style="height:5px;"> </div>
<div id="pregnancy_detail" data-role="scroller" class="scroller-content"></div>
<div style="height:76px;"> </div>
</div>
</div>

<script>
$("#pregnancy_detail").load("data.html");
</script>

</body>
</html>

The ScrollView seems to be empty. Has anyone done something like this? Any ideas you can share please? Thanks!

kendoNumericTextBox+editor not sending save event in IE10

Dear Kendo Team,
I have an issue with a grid in editable mode (incell), selectable row and navigatable.
A column is set as number, so when the grid is in edit mode, a kendoNumericTextBox is shown.
When i navigate into the cell, with the tab key, the other cells (not numeric) throw the save event binding to the grid.
All works fine in chrome, but in IE10, the event is not thrown....and the value is not updated. Only the "enter" key throws the save event for this kind of cell (=>kendoNumericTextBox)
Could you provide a solution for this issue?
Thanks in advance

Grid command buttons issue.

Here's the scenario, I have a grid (i'm using MVC wrapper to create it, but the problem is on the client so this forum should be ok...), the grid is setup for editing in popup mode. On the databound event, I have some script that alters the buttons to use my own icons rather than the default and it removes any text in the buttons as well.

This is made necessary since there is no way to customize the button's html.

Here's the script that runs on the databound event:

function updateGridButtons() {

$(".k-grid-Details")

.each(function () { styleGridButton(this, "View Details", "e-icon-viewDetails"); });

$(".k-grid-edit")

.each(function () { styleGridButton(this, "Edit", "e-icon-customEdit"); });

$(".k-grid-delete")

.each(function () { styleGridButton(this, "Delete", "e-icon-customDelete"); });

}

function styleGridButton(button, title, icon) {

$(button)

.removeClass("k-button-icontext")

.addClass("k-button-icon")

.attr("title", title)

.html("<span class=\"k-icon " + icon + "\"></span>");

}

The above script works great, it displays exactly like i want it to. The details button is a custom button, while the edit and delete are the default output of the MVC wrapper for those commands. The problem starts when I complete an edit, rather when i click the "Update" or "Cancel" button on the popup. For some reason, the buttons switch back to thier original state with the original icons and text.

I've tried binding to the click events of the update and cancel, but the change is occuring after that event. I've tried binding to the DOMNodeInserted/DOMNodeRemoved events but I cannot seem to get those events to bind or fire consistently across all browsers or all situations.

Any ideas on how to prevent the buttons from changing back to thier original state? Any help would be appreciated.

Custom Downloader for internal build .js files

I built a custom download using your tool for the last release. I now need to use the current internal build/hotfix but the custom download tool does not support internals, apparently.

How can I combine the .js files I need into one kendo.custom.min.js file? Is it simply a matter of iterating thru each file and concatenating the text into the new file? Is there an order that must be observed?

I tried this LinqPad C# script but the resulting .js file did not appear to work.

// Iterate thru .js files in KendoCustom to create kendo.custom.min.js

void Main()

{

var files = Directory.EnumerateFiles(@"C:\Users\me\Desktop\KendoCustom\", "*.js");

var outputFile = @"C:\Users\me\Desktop\KendoCustom\kendo.custom.min.js";

if (File.Exists(outputFile)) File.Delete(outputFile);

foreach (var fileName in files)

{

var contents = File.ReadAllText(fileName);

contents = "/* " + fileName + " */ " + contents + "\n\n";

File.AppendAllText(outputFile, contents);

}

Thanks,
Gary Davis

kendo grid in kendo tabs using partial view

For some reason i can get second tab (Product Details) to bind record in the grids although the GetAllProductList return records. Please advise, thank you

index.cshtml

@(Html.Kendo().TabStrip()
.Name("tabstrip")
.Items(items =>
{
items.Add().Text("Search")
.LoadContentFrom("Index", "ProductDetails")
.Selected(true);

items.Add().Text("Product Details")
.LoadContentFrom("_Product", "ProductDetails")

})
)

_Product.chtml (Partial page)

@(Html.Kendo().Grid<HH.PrductModel>()

.Name("Product")
.HtmlAttributes(new { @Style = "align:center; font-size:10px; width:950px" })
.Columns(columns =>
{

columns.Bound(p => p.ProductId).Width(95);
columns.Bound(p => p.Name).Width(120);

})

.ToolBar(toolbar => toolbar.Create())
.Sortable()
//.Pageable()
.Pageable(paging => paging
.Input(false)
.Numeric(true)

.PreviousNext(true)
.PageSizes(new int[] { 5, 10, 25, 50 })
.Refresh(false)

)
.Selectable()
.Scrollable()
.ColumnMenu(c => c.Columns(false))
.DataSource(dataSource => dataSource

.Ajax()//bind with Ajax instead server bind
.PageSize(10)
.ServerOperation(true)
.Model(model =>
{
model.Id(p => p.ProductId);

})
.Sort(sort => sort
.Add(x => x.Name).Descending())

.Read(read => read.Action("GetProductData", "ProductDetails").Type(HttpVerbs.Get))

)

)

ProductDetails controller

public ActionResult GetProductData([DataSourceRequest] DataSourceRequest request)
{
Response.Cache.SetCacheability(HttpCacheability.NoCache);
return Json(GetAllProductList().ToDataSourceResult(request), JsonRequestBehavior.AllowGet);
}

The following will return records but for some reason it would bind to grid in Product details tab

/// <summary>

/// </summary>
/// <returns></returns>
private static IEnumerable<ProductModel> GetAllProductList()
{
using (var dc = new HHEntities())
{
var result = (from a in dc.Products

select new ProductModel
{
ProductId= a.ProductId,
Name= a.Name,
Description= a.Description,
ExpiryDate= a.ExpiryDate

});
return result.Distinct().ToList();
}

}

public ActionResult _Product()
{
return PartialView();
}

ComboBox MVVM binding entire object instead of object value(MVVM Bug)

I have a ClientListItem javascript prototype with several fields such as "ClientName" and "ClientID". I have a list of these objects in a viewmodel datasource called "BrokersDatasource". It is a property of a kendo observable.

In the HTML markup I declare the combobox and bind it to the datasource with the following
<input
id="viewRequest_drpBroker"
data-role="combobox"
data-text-field="ClientName"
data-value-field="ClientID"
data-bind="source: BrokersDatasource, value: InspectionRequest.BrokerID"
/>

The list is populated correctly, the datasource is bound, the proper text appears, however the ClientID is not being bound as the value. On selection of a combobox item I am expecting the ClientID to be reflected in the viewmodels InspectionRequest.BrokerID. However instead of setting the ClientID, it is setting the entire ClientListItem instance to the BrokerID. So the actual BrokerID value is something like '{ClientName: "Generic Broker", ClientID: "44"}', when in fact it should just be "44".

The issue only occurs one way. If I set the BrokerID using viewmodel.set("InspectionRequest.BrokerID", 44), it will find and toggle the correct list item and text in the widget. However when selecting from GUI/Widget it sets the BrokerID to entire instance of the object instead of just numeric value.

The bug is present in both the latest commercial release(2012.1.515) and latest internal build(2012.1.615). I have used autocomplete and dropdownlists in a similar way with no issues encountered.

Google Instant with AutoComplete and Grid

Do you enjoy Google’s instant search feature? If so, this is the tutorial for you. Basically we want to create a widget that will update search results as you type in a text box. Google calls this “Instant”. We can achieve this same functionality by combining the AutoComplete widget and the Grid widget.

Setup the AutoComplete control.

<li>

@(Html.Kendo().AutoComplete()

.Name("BenefitID")

.Suggest(false)

.MinLength(2)

.DataSource(

ds => ds.Read(

r => r.Action("BenefitSearch", "Home").Data("setTemplateListFilters")

).ServerFiltering(true)).DataTextField("Description").HtmlAttributes(new { style="width:450px",placeHolder = "Search Existing Benefits" })

.Events(e=>e.DataBound("BenefitDataBound").Open("OnOpen"))

)

</li>

We need to set Suggest = false, otherwise the control will attempt to suggest a value within the search textbox. The magic happens in our event handlers, “BenefitDataBound” and “OnOpen”.

When the AutoComplete widget is databound, we simply want to extract the JSON data from the datasource and pass it off to a method that will create and bind a Grid.

function BenefitDataBound(e, args) {

bindGrid(this.dataSource.data());

}

function bindGrid(data) {

$("#gridResults").kendoGrid(

{

dataSource: {

data: data,

group: {

field:"Category"

}

},

change: rowSelection,

selectable: "single",

height: 430,

navigatable: true,

scrollable: {

virtual: false

},

columns: [

"ID",

"Name",

"Description"

]

}

);

}

Or if you prefer to create everything using the MVC wrappers, you can do the following:

@(Html.Kendo().Grid<Sbc.Domain.ArtifactSummary>().Name("ContentReport")

.Columns(c =>

{

c.Bound(x => x.Name);

c.Bound(x => x.Category);

c.Bound(x => x.Type);

c.Bound(x => x.Version);

c.Bound(x => x.LocalVersion).Title("Local Version");

})

.DataSource(dataSource => dataSource

.Ajax()

.PageSize(20)

.ServerOperation(false)

)

.Scrollable(x => x.Height(200))

.Sortable(sorting => sorting.SortMode(GridSortMode.SingleColumn))

)

function BenefitDataBound(e, args) {

var grid = $("#ContentReport").data("kendoGrid");

grid.dataSource.data(this.dataSource.data());

}

Lastly we need to prevent the AutoComplete widget from displaying any UI. This can be handled by the OnOpen event handler.

function OnOpen(e) {

e.preventDefault();

}

There you have it. Enjoy!

Getting checked children

Hi.

I am trying to figure out how I get only the checked children of a node, not checked grand children.

I use this code at the moment, fires when i click on a link attached to the parent:

var tree = $("#treeview").data("kendoTreeView");
var items = $(this).closest(".k-item").find(".k-group .k-item input[type=checkbox]:checked");
items.each(function() {
var getNode = $(this).closest(".k-item");
var item = tree.dataItem(getNode);
console.log(item.id);
});
}

This code gives me all checked children, grand children and so on, but i need only the children. I tried changing the .find() filter with .children() filter, but then items is empty.

Can anyone point me in the right direction? Your help is much much appreciated.
