Hello,
After I changed node's display text in client side the node become not selectable. for example I have treeview as below:
$("#treeview").kendoTreeView({
dataSource: [
{ text: "foo", id:"1", items: [
{ text: "AAA",id:"2" } ] }
]
});
I changed "AAA" to "BBB" by button click (see below code). after that I cannot select that node anymore. the node with 'BBB' function as a LABEL. Does anyone has idea how to resolve it?
$("#btn").click(function(){
var treeview = $("#treeview").data("kendoTreeView");
var myDataItem=treeview.dataSource.get(2);
var node = treeview.findByUid(myDataItem.uid);
node.text("BBB");
treeview.select(node);
});

I am using kendo grid column editor to get autocomplete values in each cell in a column.
If my selected text is digit, then its selecting [object Object] for the first time and after that if I select again different digit, it will select the digit.
And it doesn't happens with the alphabet/alphanumeric text values.
In the below code, If I am selecting "50", it is giving [object Object].
And if I am selecting Test 65/ Test, it will not change.
And if I add space in text ("50 "), them this value will also not change.
please check and resolve the issue.
$('<input data-text-field="text" data-value-field="value" data-bind="value:' + options.field + '"/>')
.appendTo(container)
.kendoAutoComplete({
autoBind: false,
suggest: true,
filter: "contains",
index: 1,
minLength: 1,
dataSource: [
{ text: "50", value: "50"},
{ text: "60", value: "60" },
{ text: "Test 65", value: "65" },
{ text: "Test", value: "23" },
{ text: "64", value: "64" },
{ text: "20", value: "20" }
]
});

First question: Can I have multiple create buttons in a Grid toolbar?
Second question: Can the buttons set the value of a column (string value) based on the button pressed).
For example, I am trying to use buttons to control if the person being added is a contractor or an employee. I have a column in my grid called Type (SwitchPersonType in datasource schema) and I want that column to be set based on the button pressed. Is this possible?
Thank you

I have a grid that is successfully fetching my json data. When the grid loads, the data is present but the paging buttons on the lower left do not work and the grid says "No items to display" on the lower right. If I change the drop down to change the number of items per page, the grid refreshes and the paging works correctly and the number of records are also displayed. Any ideas?

I initially would have expected that the dataItems() method would have returned the items in the order that they appear in the list box. However, the method does not. Are there any plans to change this? The best work around I can come up with is
var selectCols = $('#list`).data('kendoListBox');
selectCols.items().map(function(i, e) { return selectCols.dataSource.getByUid($(e).data('uid')); })
Is there a better, more durable approach that leverages public API's?
Thanks.

So if in your column specification you specify Locked:true for example
columns: [
{
field: "OrderDate",
title: "Order Date",
width: 180,
locked: true,
lockable: false,
format: "{0:MM/dd/yyyy}"
},
{
field: "ShipCountry",
width: 180,
lockable: false,
title: "Ship Country"
}
]
then you add in multiple selections so
selectable: "multiple, row",
Now if you add your change event like this
change: function(e) {
var selectedRows = this.select();
alert(JSON.stringify(selectedRows));
},
you will see the length will now be double, IE if you select 1 row then the length of selectedRows is 2 with a duplicate entry, If you remove the locked:true from the column then it gets it correct at 1. I am guessing it is creating a duplicate locked column etc.
I have confirmed this on the online examples just adding in this things.
Is this a known bug?
Is this a new bug?
Do you know a way around this so you can actually tell the accurate elements selected?

I have a Kendo listbox with a toolbar that allows sorting (up/down) and delete of a list item. When my listbox has enough items that extends it beyond the view of a mobile device, scrolling down causes the toolbar to scroll off screen. Because of this, if a user wants to move the bottom item of the listbox up, they have to scroll down, select the item, then scroll back up to access the toolbar actions, which makes for poor user experience. How can make the toolbar scroll along with list, or even just duplicate the toolbar at the bottom of the list?

I am using two listboxes, connected with each other, that allow drag and drop between the two. While using the reorder code found in another thread fixes the issue with reordering items within the same list, it doesn't address the issue when dragging and dropping an item from one listbox to the other. I understand that is because this isn't a "reorder" action, it is a "drop" action. I've tried many different angles, like using the "add" event, but there is no "offset" property in the (e) object.
How can I accomplish the same thing, that is, keep the dropped item in the order it is visually dropped?

I cannot understand the following sentence from https://goo.gl/q14C6L very well
The dataSource is designed to work with flat (not nested) data. Defining a 'complex' objects in the schema.model is not supported
For this reason I think there is on schema model the from property which allow to rename / alias data fields ( for example from a foreign remote server )
Yes , but if dataSource doesn't support complex object why :
- in the schema.model.<fieldN>.type is present a 'object' type ?
- in the grid for example is available dot notation to retrieve in some place a nested value on model ?? es: Category.name - is it not in contrast with previous sentence ?
Also - What is the role of field.type == object during various operation ?? for example if I have a datasource with a field of type object in a grid, it is normally rendered like a string. How is it related to defaultValue ??
So I cannot understand why documentation is not coherent
Thanks
