HI,
I made an interface with some controls, from Kendo. It's a number, textbox and dropdownlist. What it does it's create many copies of itself by the press of the "+" button and delete a row by the press of it's "-" button.

Here's the code:

{% extends "saloons/templates/base.html" %}

{% from "ui/forms/macro.html" import wtform %}

{% block content %}

<form method="POST" action="">

<table>

<tr>

<td>{{ form.order_date.label }}</td>

<td>{{ form.order_date }}</td>

</tr>

</table>

<div id="grid-users" class="grid-content" style="text-align: center; width: 100%!important">

<table id="grid">

<thead>

<tr>

<th data-field="number" style="text-align: center">Nro.</th>

<th data-field="item" style="text-align: center">Articulo</th>

<th data-field="staff" style="text-align: center">Usuario</th>

<th data-field="button" style="text-align: center">Añadir/Remover</th>

</tr>

</thead>

<tbody id="pedidos">

<tr>

<td>1.</td>

<td>{{ form.item }}</td>

<td>{{ form.staff }}</td>

<td><button type="button" id="add_textbox">+</button></td>

</tr>

</tbody>

</table>

<center>

<div class="buttons">{{ form.save }}</div>

</center>

</div>

</form>

<script type="text/javascript">

$(function() {

$("#save").attr('class','k-button');

$("#c0").attr('class', 'k-input');

var sel = $("#t0").clone();

var sel2 = $("#c0").clone();

var i = 1;

var data = "{{ inventory }}".replace("[", "").replace("]", "");

var a = data.split(",");

for(j=0;j<a.length;j++)

{

if(j == 0){

a[j] = a[j].substring(2,a[j].length -1);

}

else

{

a[j] = a[j].substring(3,a[j].length -1);

}

$("#add_textbox").attr('class', 'k-button');

$("#add_textbox").live('click', function() {

i++;

$("#pedidos").append('<tr>' +

'<td>'+ i +'. </td>' +

'<td id="c'+ i +'"></td>' +

'<td id="t'+ i +'"></td>' +

'<td><button type="button" rel="del" class="k-button">-</button></td>' +

'</tr>');

$(sel2).attr('id',"tc"+i);

$(sel).attr('id',"ts"+i);

$(sel2).appendTo("#c"+i);

$(sel).appendTo("#t"+i);

$("#tc"+i).css('width', 180);

$("#tc"+i).kendoAutoComplete({

dataSource: a

});

sel = $(sel).clone();

sel2 = $(sel2).clone();

$("#ts"+i).css('width', 270);

$("#ts"+i).kendoDropDownList();

});

$("button[rel=del]").live('click', function() {

$(this).parent().parent().remove();

i--;

var a2 = 0;

$("#pedidos tr").each(function(i){

a2++;

$(this).find("td:first").html(a2);

});

$("#order_date").kendoDatePicker({

min: new Date(),

value: new Date(),

format: "dd/MM/yyyy"

});

$("#order_date").attr('disabled','disabled');

$("#grid").kendoGrid({

height: 460,

sortable: false,

columns: [{field:"number", width:40},

{field:"item", width:40},

{field:"staff", width:80, editor: function(container, options){

}},

{field:"button", width:40}]

});

$("#t0").css('width', 270);

$("#t0").kendoDropDownList();

$("#c0").css('width', 180);

$("#c0").kendoAutoComplete({

dataSource: a

});

</script>

{% endblock %}

Happens that at some point when you start deleting rows, some dropdowns and textboxes are assigned to the wrong rows. At first I thought that it was because some ids didn't match when making the recount in the minus button, but I already tried that.

Can you help on this one, please?

[Solved] TabStrip is blank when loading grid into tab

I am attempting to load a grid into the content of the first tab in a tabstrip. I have tried several variations of the code and how the grid loads, including via the "activate" event. Here is a jsfiddle of a basic version of the code. The grid works with the tabstrip code commented out. It seems like it would be a simple oversight.

[Solved] Adjust Z index or some other magic

I have a menu inside a splitter and when it expands, it expands outside the spitter, and the splitter needs to be resized to see the menu items.

Is it possible to change the order of a menu so the overflow is not hidden and it expands over the spitter?

This post: http://www.kendoui.com/forums/ui/menu/menu-z-index.aspx and http://www.kendoui.com/forums/ui/menu/menu-splitter-hides-the-pop-ups.aspx don't work. All this does is cause scrollbars to show on the splitter pane containing the menu, it doesn't actually make the menu items expand over the top of the splitter.

Many foreign keys in one grid...

The Grid:

$('#' + idGrid).kendoGrid({

dataSource: dataSource,

height: 400,

toolbar: [{name: "create", text:"Create County"}],

columns: [

{ field:"_id", title: "ID", width: "50px" },

{ field: "_status", values: status, title:"Status", width: "100px", editor: status_dropdown },

{ field: "_country_id", title: "Country", values: countries, width: "50px", editor: country_dropdown },

{ field: "_county_id", title: "County", values: counties, width: "50px", editor: county_dropdown },

{ field: "code", title: "Code", width: "150px" },

{ field: "name", title: "Name", width: "150px"},

{ field: "localname", title: "Localname", width: "150px"},

{ command: ["edit", "destroy"], title: " ", width: "200px" }],

editable: "popup",

sortable: {

mode: "multiple",

allowUnsort: true

},

filterable: true,

resizable: true,

groupable: true,

pageable: {

pageSize: 30,

refresh: true

}

});

the fields "_status", "_country_id", "_county_id" have integer values in database, but we want to show string values to the user. So we use the "values" parameter that is an array. In the case of _status for example we use:

var status = [{

"value": 0,

"text": "Disabled"

}, {

"value": 1,

"text": "Enabled"

}];

Everything works fine...

The other two, however are arrays that are created from datasources that are populated from the server. That means the action is asynchronous. So if you try creating datasource->array->grid asynchronously the array might not be populated so the grid shows integer values instead.

If i have one such datasource i use the "change" event of the datasource to create the array and then the grid. For example:

var countiesData;

var counties = new Array();

var countiesDataSource = new kendo.data.DataSource({

transport: {

read: {

url: "../order_new/county.php"

}

},

schema: {

data: "data"

},

change: function(e) {

countiesData = this.data();

console.log(countiesData);

var counties = new Array();

for (var i = 0; i < countiesData.length; i++) {

var dataItem = countiesData[i];

counties.push({

"value": parseInt(dataItem._id),

"text": dataItem.name

});

}

//here goes the previous code of grid creation

}

This works just fine... But what should i do now that i have two (or maybe more) foreign keys that need integer->string modification?
Just to know, i have tried creating the second datasource inside the change event of the first and then creating the grid inside the change event of the second. Doesn't work! And is far from elegant solution. Any ideas telerik team and users?

Amending Template to inc. items such as TabStrip or PanelBar

Is this even possible?

Orignally I was hoping to be able to have TabStrips inside my Editor Template. The idea being that instead of adding new items to the list, I could choose to add existing items. (for example, I have a Customer Grid and I want to add Items Owned by customer, so I have a sub grid showing Items Owned, I want to be able to add both a entirely new item, and an existing item).

I've tried to use the example TabStrip and PanelBar without luck.

@model Model.Test

@(Html.Kendo().PanelBar()

.Name("panelbar")

.ExpandMode(PanelBarExpandMode.Single)

.HtmlAttributes(new { style = "width:300px" })

.Items(panelbar =>

{

panelbar.Add().Text("My Teammates")

.Expanded(true)

.Content(@<div style="padding: 10px;">

<div class="teamMate">

<h2>Andrew Fuller</h2>

<p>Team Lead</p>

</div>

<div class="teamMate">

<h2>Nancy Leverling</h2>

<p>Sales Associate</p>

</div>

<div class="teamMate">

<h2>Robert King</h2>

<p>Business System Analyst</p>

</div>

</div>);

panelbar.Add().Text("Projects")

.Items(projects =>

{

projects.Add().Text("New Business Plan");

projects.Add().Text("Sales Forecasts")

.Items(forecasts =>

{

forecasts.Add().Text("Q1 Forecast");

forecasts.Add().Text("Q2 Forecast");

forecasts.Add().Text("Q3 Forecast");

forecasts.Add().Text("Q4 Forecast");

});

projects.Add().Text("Sales Reports");

});

panelbar.Add().Text("Programs")

.Items(programs =>

{

programs.Add().Text("Monday");

programs.Add().Text("Tuesday");

programs.Add().Text("Wednesday");

programs.Add().Text("Thursday");

programs.Add().Text("Friday");

});

panelbar.Add().Text("Communication").Enabled(false);

})

)

Both of the times I've tried (with TabStrips and PanelBars) I get Invalid Template, erroring on kendo.dataviz.min.js.

If this cannot be done the only other way I can think is to create 2 custom toolbar buttons which will load a popup which replicates the Add (1 add a new item and 1 add an existing item), but I cannot find any examples of a custom toolbar with a popup (only the ViewDetail example which is inline).

As you can most probably tell, I am quite new to this!

Thanks,

Editor

Adding additional data on ajax grid post not using js function name string

I have a grid which is using ajax to retrieve data using the "read" method. This requires additional data to be posted to the controller. This works good using a javascript function to send the additional data. And their are many examples of this being done. But due to requirements I would like to create the actual javascript function inside the "Data" call instead of specifying the string for the javascript function name. Based on the intellisense I think this is possible but not sure of the syntax.

So the example below shows what works (Read #1) and what I want to do instead (Read #2).

@(Html.Kendo().Grid<Tabs.Viewer.UI.WebViewer.Models.MyModel>()
.Name("Grid")
.Columns(columns => {
columns.Bound(p => p.Email).Title("column1");
columns.Bound(p => p.Description).Title("column2");
.DataSource(dataSource => dataSource
.Ajax()
.Model(model => model.Id(p => p.myId))
// Read #1 This works fine but do not want to specify the method name
.Read(read => read.Action("PopulateAlertGrid", "ProductAlert").Data("onAdditionalProductAlertGridData"))
// Read #2 Note: I want to add the actual js code instead of the above line.
.Read(read => read.Action("PopulateAlertGrid", "ProductAlert").Data(function myMethod(){...})
))

So can someone share the syntax to put the js code in the data call or if this is possible?

Thanks, Dan

Thanks.
