Hey i've a Problem with KendoTreeview. I build a TreeView with a json Datasource
[
{"id":1,"text":"foo","expanded":true,"items":
[
{"id":2,"text":"foo2","expanded":false,"checked":false},
{"id":3,"text":"foo2-1","expanded":false,"items":
[
{"id":4,"text":"foo3","expanded":false,"checked":false}
]
,"checked":false}
],"checked":true
}
]
JS Code:
$(document).ready(function() {
var dataSource = new kendo.data.HierarchicalDataSource({
transport: {
read: {
url: servlet,
datatype: "json",
contentType: "application/json"
}

},
schema: {
model: {
children: "items",
id: "id"
},
data: function(data) {
var dataArray = eval(data);
return dataArray;
}
}
});

var treeView = $("#treeView").kendoTreeView({

dataSource: dataSource,
dataTextField: "text",
checkboxes: {
checkChildren: true
}
});
It works well but if i use checkChildren: true the pre check is not working. if i use only checkboxes: true without checkchildren pre check works but not check all childs. What is wrong ?

Save Event Listener not reading field changed from edit popup

Hi

I am trying to test the save function for an edit to catch the value entered and field id.

However this does not seem to work with the edit popup where I listen to "e.values.name".

Simply changing the edit to "mode: popup" from inline breaks the save function.

Help appreciated

[Solved] line chart missing category labels multiple series

Hi,

In the attached chart I have multiple dynamic line series on the chart which last for varying periods of time however the category axis seems to be generating it's values from the very first data point, so if the first one only lasts for one month then that's all the category axis will represent even though the other lines last for longer. Is there a way to get the category axis to generate its labels dependent on the longest line rather than the first?

Thanks.

Identify non-sortable columns

We have several grids that have some non-sortable columns and we would like to identify which columns are sortable with some type of visual indicator.

Is there an accepted way to do this. I was thinking of maybe using a sort icon for the sortable columns, is this supported out of the box or do I need to figure out something clever with jquery?

kendo grid hide column dynamically

I tried to hideColumn(k) in databound event when the whole column has null values. But because my first row of header is colspan of 6 columns, so it did not hide properly. I could only hide the first column or the second column (contains all the columns). I tried grid.columns[1].hideColumn(3) but failed as hideColumn is related to grid.
How can I achieve that?

columns: [
{ field: "facname", title: "Facility", attributes: { style: "text-align:left" }, width: "200px" },
{
title: "",
columns: [
{ field: "envelopes[0]", title: "Food", attributes: { style: "text-align:right" }, width: "90px", template: "#= envelopes[0] == null ? '-' : kendo.toString(envelopes[0], 'c0') #" },

Thanks.

Ipad issue: cascading dropdown is blank

Hello,

Infos:

I'm working with kendo 2014.1.318 in an asp.net MVC application : I use the wrappers.

I have an issue with the cascading dropdown on Ipad (IOS 8.1 safari)
The issue is not reproducible on windows browsers, I tried ie9, chrome, firefox and safari for windows : no problem

So, here is the problem:

I have a first dropdown containing a list of brands.
I have a second dropdown with a list of models

First I select a brand
My dropdown "models" is populated => ok

Then I select a brand with a few models

My dropdown "models" is populated but the popup is not painted: it's all white (see attached screenshot)

But if I touch the popup a few time: the items appears

If I select a brand with a lot of models : no problem

So I think this issue only appears when the number of items in the "models" dropdown is not big enough to activate the scroll in the popup

Has anyone experienced this issue?

Do you have any ideas how to resolve this ?

[Solved] Combine Category+SubCategory in Bar Graph CategoryAxis text

I've got a bar graph that is bound to the result of a query.
The query may be grouped by Category, or Category + SubCategory

The data is displayed visually correctly, however, I'm only able to display either the category OR the subcategory across the category axis.
How can I A. display both, and B. wrap the text so that it will fit?

MaskedEditBox Missing Last 0

http://dojo.telerik.com/EXODI

creating a mask as described below, the last character should be the number zero.
$("#maskedtextbox").kendoMaskedTextBox({
mask: "\\1\\0A\\ 00\\ 00\\ 000\\ 00\\ L0\\ \\00",
value: "100 14 36 085 17 W6 00"
});

when the mask renders it renders as 100 14 36 085 17 W6 0_
it loses the last character. If the last character is not a zero then it seems to work fine but must be some wierd logic in there where it's causing the last number to be lost.

Line chart category axis and chart dots

I'm trying to create a chart with the x-axis (horizontal) being a date/timeline and the y-axis (vertical) being the values. I want to show each value in the chart (4 values per year), but only displaying the year in the x-axis.

I've been trying to work with the settings on the categoryAxis object, but can't seem to get it to work.

I have illustrated the issue below in two images.

One having the correct x-axis, but not the correct number of dots and the other one having the correct number of dots, but not the correct x-axis.

[Solved] Doing math on aggregates

I need a couple of my aggregate fields to be calculated based on the aggregates of other columns. Is this possible?

For example, if I have the following fields:

Revenue, Cost, Margin (Revenue - Cost), Margin % (Margin / Revenue)

For aggregating these fields, sum works fine on Revenue, Cost, and Margin. However, if I want to find the total Margin %, I need to do: SUM(Margin) / SUM(Revenue). Is there a way to do this with the DataSource?
