How to send data to the controller from the Kendo UI TreeView - kendo-ui

I have two TreeViews, one has a list of countries, and the other is empty, now I want drag and drop selected countries into the second tree-view. I don't know how to send data to the controller from the TreeView and there is also some text field on the page in a form. So, how can I send both the form data and the TreeView's data to the controller.
Here is the code for the second tree-view which is empty and I want to add the selected nodes to:
#(Html.Kendo().TreeView()
.Name("treeview-right")
.DragAndDrop(true)
.Events(events => events
.Drag("onDrag")
.Drop("onDrop")
)
)

Please try with the below code snippet.

<div style="border: 1px solid green;">
<div id="treeview-left"></div>

<div style="border: 1px solid red;">

]
}
]
});
var selectedID;
function SaveData() {
selectedID = '';
var tv = $("#treeview-right").data("kendoTreeView");
selectedID = getRecursiveNodeText(tv.dataSource.view());

//nodeview[i].text; You can also access text here

Kendo UI grid drag&drop placeholder

I have grid with drag&drop functionality:
var data = [
{ id: 1, text: "text 1", position: 0 },
{ id: 2, text: "text 2", position: 1 },
{ id: 3, text: "text 3", position: 2 }
]
var dataSource = new kendo.data.DataSource({
data: data,
schema: {
model: {
id: "id",
fields: {
id: { type: "number" },
text: { type: "string" },
position: { type: "number" }
}
}
}
});
var grid = $("#grid").kendoGrid({
dataSource: dataSource,
scrollable: false,
columns: ["id", "text", "position"]
}).data("kendoGrid");
grid.table.kendoDraggable({
filter: "tbody > tr",
group: "gridGroup",
threshold: 100,
hint: function(e) {
return $('<div class="k-grid k-widget"><table><tbody><tr>' + e.html() + '</tr></tbody></table></div>');
}
});
grid.table.kendoDropTarget({
group: "gridGroup",
drop: function(e) {
e.draggable.hint.hide();
var target = dataSource.getByUid($(e.draggable.currentTarget).data("uid")),
dest = $(document.elementFromPoint(e.clientX, e.clientY));
if (dest.is("th")) {
return;
}
dest = dataSource.getByUid(dest.parent().data("uid"));
//not on same item
if (target.get("id") !== dest.get("id")) {
//reorder the items
var tmp = target.get("position");
target.set("position", dest.get("position"));
dest.set("position", tmp);
dataSource.sort({ field: "position", dir: "asc" });
}
}
});
(working example: http://jsfiddle.net/JBeQn/ )
Is it possible to show the placeholder where the row will be dropped? From current implementation it's not obvious. So I would like to make something like this:
http://demos.telerik.com/kendo-ui/sortable/events
or this:
http://jsfiddle.net/bgrins/tzYbU/
In the demo above placeholder is showed and it's quite easy to understand where the row will be dropped.
So any ideas?

Set the selected text or value for a KendoDropDownList

I'm using Durandal and Kendo UI. My current problem is the edit popup event on my grid. I cannot seem to set the selected value on my dropdown.
I can debug and inspect, and I indeed do see the correct value of e.model.InstrumentName nicely populated.
How can I set the value/text of those dropdowns in edit mode ?
Here's my grid init:
positGrid = $("#positGrid").kendoGrid({
dataSource: datasource,
columnMenu: false,
{
field: "portfolioName", title: "Portfolio Name",
editor: portfolioDropDownEditor, template: "#=portfolioName#"
},
{
field: "InstrumentName",
width: "220px",
editor: instrumentsDropDownEditor, template: "#=InstrumentName#",
},
edit: function (e) {
var instrDropDown = $('#InstrumentName').data("kendoDropDownList");
var portfDropDown = $('#portfolioName').data("kendoDropDownList");
instrDropDown.list.width(350); // let's widen the INSTRUMENT dropdown list
if (!e.model.isNew()) { // set to current valuet
//instrDropDown.text(e.model.InstrumentName); // not working...
instrDropDown.select(1);
//portfDropDown.text();
}
},
filterable: true,
sortable: true,
pageable: true,
editable: "popup",
});
Here's my Editor Template for the dropdown:
function instrumentsDropDownEditor(container, options) {
// INIT INSTRUMENT DROPDOWN !
var dropDown = $('<input id="InstrumentName" name="InstrumentName">');
dropDown.appendTo(container);
dropDown.kendoDropDownList({
dataTextField: "name",
dataValueField: "id",
dataSource: {
type: "json",
transport: {
read: "/api/breeze/GetInstruments"
},
},
pageSize: 6,
select: onSelect,
change: function () { },
optionLabel: "Choose an instrument"
}).appendTo(container);
}
thanks a lot

Your editor configuration is bit unlucky for grid, anyway i have updated my ans on provided code avoiding manual selections:
Assumptions: Instrument dropdown editor only (leaving other fields as strings), Dummy data for grid
<div id="positGrid"></div>

{ PositionId: 2, Portfolio: "John Doe", Instrument: { IID: 2, IName: "Auth1" }, NumOfContracts: 33, BuySell: "sfsf" }
],

Kendo UI toolbar buttons

I am using a Kendo UI grid, which looks like this:
function refreshGrid()
{
$(".k-pager-refresh.k-link").click();
}
var editWindow;
var fields= {FullName: {type: "string"}, Email: {type: "string"}, LogCreateDate: {type: "date"}};
var gridColumns =
[{
width: 90,
command: {
name: "edit",
text: "Edit",
click: function(e) {
var dataItem = this.dataItem($(e.currentTarget).closest("tr"));
editWindow = $("#edit").kendoWindow({
title: "Edit User",
modal: true,
visible: false,
resizable: false,
width: 800,
height: 400,
content: 'myediturl' + dataItem.ID
});
editWindow.data("kendoWindow").center().open();
return false;
}
}
},
{
width: 90,
command: {
name: "delete",
text: "Delete",
click: function(e) {
//alert(this.dataItem($(e.currentTarget).closest("tr")).ID);
var id = this.dataItem($(e.currentTarget).closest("tr")).ID;
if (confirm("Are you sure you want to delete this user?"))
{
$.ajax({
type: 'POST',
url: '#Url.Action("deleteuser","admin",null, "http")' + "/" + this.dataItem($(e.currentTarget).closest("tr")).ID,
success: function (param) { refreshGrid(); },
async: false
});
}
return false;
}
}
},
{
field: "FullName",
title: "Full Name",
type: "string"
},
{
field: "Email",
title: "Email",
type: "string"
},
{
field: "LogCreateDate",
title: "Created",
type: "date",
template: '#= kendo.toString(LogCreateDate,"MM/dd/yyyy") #'
}];
//getSorts the columns of the grid
function getColumns() {
//Parsing the set of columns into a more digestable form
var columns = "";
for (var col in gridColumns) {
if (!!gridColumns[col].field)
{
if (columns.length > 0) {
columns += ";";
}
columns += gridColumns[col].field + "," + gridColumns[col].type;
}
}
return columns;
}
function getSorts(sortObject) {
if (!(sortObject)) {
return "";
}
//Getting the row sort object
var arr = sortObject;
if ((arr) && (arr.length == 0)) {
return "";
}
//Parsing the sort object into a more digestable form
var columnSet = getColumns();
var returnValue = "";
for (var index in arr) {
var type = "";
for (var col in gridColumns) {
if (gridColumns[col].field === arr[index].field) {
type = gridColumns[col].type;
}
}
returnValue += ((returnValue.length > 0) ? (";") : ("")) + arr[index].field + "," + (arr[index].dir === "asc") + "," + type;
}
return returnValue;
}
var grid;
$(function () {
$("#grid").kendoGrid({
dataSource: {
transport: {
read: {
url: "mydatasourceurl",
type: "POST",
},
parameterMap: function (data, type) {
data.filters = JSON.stringify(data.filter);
data.columns = JSON.stringify(getColumns());
data.sorts = JSON.stringify(getSorts(data.sort));
console.log(data);
return data;
}
},
schema: {
fields: fields,
data: "Data",
total: "Total"
},
pageSize: 10,
serverPaging: true,
serverFiltering: true,
serverSorting: true
},
toolbar: [{
name: "Add",
text: "Add new record",
click: function(e){console.log("foo"); return false;}
}],
height: 392,
groupable: false,
sortable: true,
filterable: true,
pageable: {
refresh: true,
pageSizes: true
},
columns: gridColumns
});
grid = $("#grid").data("kendoGrid");
});
My create toolbar action is not triggered on click. How can I resolve this problem, is Kendo UI able to handle toolbar click events? The best solution I came up with looks like this:
$(".k-button.k-button-icontext.k-grid-add").click(function () {
//If the window doesn't exist yet, we create and initialize it
if (!grids[gridContainerID].addWindow.data("kendoWindow")) {
grids[gridContainerID].addWindow.kendoWindow({
title: "Add " + entityName,
width: "60%",
height: "60%",
close: onClose,
open: onAddOpen,
content: addUrl
});
}
//Otherwise we just open it
else {
grids[gridContainerID].addWindow.data("kendoWindow").open();
}
//Centralizing and refreshing to prepare the layout
grids[gridContainerID].addWindow.data("kendoWindow").center();
grids[gridContainerID].addWindow.data("kendoWindow").refresh();
return false;
});
Thanks in advance.
Instead of using that complex selector use the one that Kendo UI creates from name:
toolbar: [
{
name: "Add",
text: "Add new record",
click: function(e){console.log("foo"); return false;}
}
],
and then:
$(".k-grid-Add", "#grid").bind("click", function (ev) {
// your code
alert("Hello");
});
In kendogrid docs here shows that there is no click configuration for grid toolbar buttons like grid.colums.commands.
To solve this problem you can reference following steps:
create a template for toolbar
<script id="grid_toolbar" type="text/x-kendo-template">
<button class="k-button" id="grid_toolbar_queryBtn">Query</button>
</script>
apply tempate to toolbar
toolbar:[{text:"",template: kendo.template($("#grid_toolbar").html())}]
add event listener to button
$("#grid_toolbar_queryBtn").click(function(e) {
console.log("[DEBUG MESSAGE] ", "query button clicked!");
});

KendoGrid doesn't work in kendoTabStrip

I'm using kendoTabStrip as is shown on KendoUI Page. In my case in each div I have rendered partial view. In a few of my partial views I have additionaly kendoGrid.
Problem
When I reload page in any tab and go to tab which contain kendoGrid then it do not work correctly. For example: I'm on tab#0 and go for tab#3 which contain kendoGrid with pagination, then pagination is not display. But when I reload it then pagination works fine.
What can I do to my Grids works inside TabStrip?
Any help would be appreciated.
UPDATE
My implementation of tabstrip
$("#tabStrip").kendoTabStrip({
animation: { open: { effects: false} },
select: function (e) {
document.location.hash = 'tab-' + $(e.item).index();
}
});
var tabStrip = $('#tabStrip').data('kendoTabStrip');
var tabId = 0;
var scheduledId = 0;
if (document.location.hash.match(/tab-/) == 'tab-') {
tabId = document.location.hash.substr(5);
}
if (document.location.hash.match(/scheduled-/) == 'scheduled-') {
tabId = 1;
scheduledId = document.location.hash.substr(11);
editSchedule('/admin/Course/Scheduled/' + scheduledId + '/Edit/' );
}
tabStrip.select(tabStrip.tabGroup.children('li').eq(tabId));
So I need it to make some rewrites from controller.
To fix this problem we must change :
$("#tabStrip").kendoTabStrip({
animation: { open: { effects: false} },
select: function (e) {
document.location.hash = 'tab-' + $(e.item).index();
}
});
for:
$("#tabStrip").kendoTabStrip({
animation: { open: { effects: false} },
select: function (e) {
document.location.hash = 'tab-' + $(e.item).index();
},
activate: function(e) {
$(e.contentElement).find('.k-state-active [data-role="grid"]').each(function() {
$(this).data("kendoGrid").refresh();
});
}
});
Event activate is 'Triggered just after a tab is being made visible, but before the end of the animation'. So we must refresh our grids then becouse js counts widths of hidden elements wrong.
I put together an example of Grids working inside of a TabStrip: http://jsfiddle.net/dpeaep/SJ85S/. Maybe, I am missing part of what you are asking in your question. If so, you can modify the jsfiddle to clarify what the problem is.

jqGrid and Google Chart API

Is it possible to add graphs using the Google Chart API or any other graph to one column of jqGrid? If it is possible, how? I need to filter each row of jqGrid and show a graph of that particular row in the last column of jqGrid.
You could use a custom formatter:
<script type="text/javascript">
$(function () {
$('#myGrid').jqGrid({
url: '#Url.Action("Data")',
datatype: 'json',
colNames: [ 'Foo', 'Bar', 'Chart' ],
colModel: [
{ name: 'foo', index: 'foo' },
{ name: 'bar', index: 'bar' },
{ name: 'chart', index: 'chart', formatter: chartFormatter },
]
});
});
function chartFormatter(el, cval, opts) {
return '<img src="' + el + '" alt="chart" title="" />';
}
</script>
<div style="height: 500px;">
<table id="myGrid"></table>
</div>
and your controller would return the corresponding Google Chart URLs:
public ActionResult Data()
{
return Json(new
{
rows = new[]
{
new { id = 1, cell = new[] { "foo 1", "bar 1", "https://chart.googleapis.com/chart?cht=p3&chd=t:60,40&chs=250x100&chl=Hello|World" } },
new { id = 2, cell = new[] { "foo 2", "bar 2", "https://chart.googleapis.com/chart?cht=p3&chd=t:60,40&chs=250x100&chl=Hello|World" } },
}
}, JsonRequestBehavior.AllowGet);
}
which gives:
