Hi,
I have the following code in a global.js library:
$.ajaxSetup({ // A pre-request callback function used to modify the xhr object before it is sent beforeSend: function(xhr){ // Set csrf if request type is POST, PUT or DELETE if (this.type !== "GET") { xhr.setRequestHeader(csrfHeader, csrfToken); } }});This set the csrf token for any REST call that modifies data (POST, PUT, DELETE).
The problem is that the Upload widget does not use it, and the server requests are being rejected due to missing authorization (403 Response). This forces me to init. my Upload widget with the following callback:
upload: function(e) { // Adds the csrf tokens to perform POST REST calls const xhr = e.XMLHttpRequest; if (xhr) { xhr.addEventListener("readystatechange", function() { if (xhr.readyState === 1 /* OPENED */) { xhr.setRequestHeader(csrfHeader, csrfToken); } }); }}
Please advise why this is necessary and why this is required. Does the Upload not use jQuery to execute the Ajax calls?
Thanks
Grant

I'm using the multselect dropdown which is being populated from a db, how can I capture what the users is typing in the box, so I can filter based off of what the user is typing?
Example: if they start typing:
John
i want to pass John to my service and filter the users that are named John.
If I use var x = $('name').data("kendoMultiSelect').text();
I get an error: Cannot read property 'text' of undefined. Is there another way to grab the text from the multiselect?

Hi,
Currently we have data that 1 parent can have multiple children meanwhile a child can belongs to multiple parents. Does treelist support this scenario?
Per what we see now the child will be placed under only 1 parent (maybe the 1st one) but other parents don't have this child available.
Thanks.

Hello,
There is a question that needs to be solved first.
Q. How do multiple dropdownlists use a single datasource?
This question is not "showing the same data".
(call by value)
"Accessing only one data source address that shares data attributes, changed current values, etc."
(call by address)
If this question is resolved, you should move on to the next question.
The solution I want is this:
All dropdownlists exist in multiple rows in a grid.
If you selected data 0 in row 0, you should not be able to select data 0 in another row.
I've seen the example below, but it's not a way to disable the data I've selected, only to manually disable it.
What is the way?

I have a numericTextBox and I would like the user to be able to enter a percentage in either of two formats. The end result should always display the number as a percentage but store it as a decimal. For example, the user should be able to either enter .10 or 10% in the box. The screen should then show 10% when the user tabs out but send .1 when the form is submitted. Here is what I have so far:
$("#myPercentageChoice").kendoNumericTextBox({ format: "p1", spinners: false, value: 0, decimals: 3});

Hi,
I'm using 2019.3.1023 version. I have a treelist which retrieving data from remote source. When user select a time range in a list the treelist will be triggered to re-fetch the data with the new selected parameter. The datasource is updated succussfully and treelist is refreshed. But the pager is not updated accordingly.
The treelist configuration:
$('#gridtable').kendoTreeList({ autoBind: false, dataSource: { transport: { read: { url: top.$.rootUrl + '/PPM_Contract/Contract/GetList', dataType: "json", data: function () { return { queryJson: JSON.stringify({ // parameters send to remote source }) }; } } }, schema: { data: "data", total: function (response) { return response.data.length; }, model: { id: "F_Id", parentId: "externalId", expanded: true, fields: { // some fields setting } } } }, filterable: true, sortable: true, resizable: true, selectable: true, pageable: { pageSize: 100 }, dataBound: function (e) { // some logic for styles }, columns:[ // some columns ] });
The trigger of refreshing the treelist:
// some parameter assignment// then call read method on datasource$("#gridtable").data("kendoTreeList").dataSource.read();
With first selection of the parameter, 124 items are returned and 2 pages initialized, which is correct (attached as 1stTry.png).
With second selection, 248 items returned, total number is updated but the pager is not (should be 3 pages but stays as 2. Attached as 2ndTry.png).
How to refresh the pager with datasource?
Thanks.

Hello.
Currently I know how to filter Server true / false and I'm using filterable.
However, both methods have their advantages and disadvantages and are looking for more efficient ways.
1. Server filtering: true
The advantage of this method is that it is very fast.
However, since you only search within the page called Limit, you cannot perform filtering on all data.
2. Server Filtering: false
The advantages and disadvantages of this approach are the opposite of true server filtering.
You can query and filter all the data in the database.
However, if tens of thousands or hundreds of thousands of data passes, there will be a delay of several tens of seconds depending on the network line.
You can also create a custom filter to do a Query, but I don't think it's a good idea because it requires extra work on every field that needs filtering.
Is there a more efficient filtering method inside Kendo?

Hello,
I often use custom editors.
But when using the dropdown list
$ ("# ..."). data ('kendoDropDownList');
I need to access the editor in the form, but I don't know what goes into # ...
If you created this editor statically, you would have an ID, but if you create a custom one, you will not have a separate ID.
My custom editor looks like this, and the ID I tried was the same as the string output in options.field.
dayDropDownEditor : function (container, options) { $('<input id="operDay" data-bind="value:' + options.field + '"/>') .appendTo(container) .kendoDropDownList({ suggest: true, dataSource: [ {name:'월', operDay: '월요일', isDeleted: true }, {name:'화', operDay: '화요일', isDeleted: false }, {name:'수', operDay: '수요일', isDeleted: true }, {name:'목', operDay: '목요일', isDeleted: false }, {name:'금', operDay: '금요일', isDeleted: false }, {name:'토', operDay: '토요일', isDeleted: false }, {name:'일', operDay: '일요일', isDeleted: false } ], dataTextField: 'operDay', dataValueField: 'operDay', valuePrimitive: true, select: function(e){ alert(JSON.stringify(options.field)); }, change: function(e) { }, template: kendo.template($("#template").html()) });}
"fn1": function() { var dropdown = $("#operDay").data("kendoDropDownList"); var oranges = dropdown.dataSource.get(2); oranges.set("isDeleted", true); }What data should be inside # ... for me to access .data ('kendoDropDownList')?
