How to center a window on first open and maintain pinned position?

Hi!

I'm using this code to open a window:

var ssButton = $("#server-settings-button")
    .bind("click", function () {
          ssWindow.data("kendoWindow").open().center();
    });

Window is opened centered, but if I move it, pin it, close it and try to open it again it opens centered and doesn't maintain pinned position.

How can open it centered but still maintain pinned position?

Setting POST and ContentType for READ fails To Create JSON Payload

Hello -

This is an offshoot of: http://www.telerik.com/forums/problem-with-datasource-post-request-for-read-operation

Unfortunately, that thread is closed so I can't follow-up.

However, it seems to me that there's a potential bug with DataSource (used inside a Kendo Grid) when doing a READ using POST and contentType = "application/json".

Here is my javascript:

dataSource: {

transport: {

read: {

url: "rest/books",

type: "POST",

contentType: "application/json; charset=utf-8"

}

...

However, based on examining the network traffic, here's the POST request information:

Remote Address:[::1]:8082

Request URL:rest/books

Request Method:POST

Status Code:400 Bad Request

Request Headersview source

Accept:*/*

Accept-Encoding:gzip, deflate

Accept-Language:en-US,en;q=0.8

Cache-Control:no-cache

Connection:keep-alive

Content-Length:31

Content-Type:application/json; charset=UTF-8

Host:localhost:8082

Origin:http://localhost:8081

Pragma:no-cache

Referer:http://localhost:8081/

User-Agent:Mozilla/5.0 (Macintosh; Intel Mac OS X 10_9_5) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/40.0.2214.91 Safari/537.36

Request Payload

take=5&skip=0&page=1&pageSize=5

You can see in that very last line, the paging parameters for the Grid are being sent as key/value pairs (URL param encoding) instead of JSON.

I would think that since I'm setting contentType to JSON, and using a POST, that internally the DataSource would JSON encode my paging parameters.

The workaround (based on info in the link above) is to override the parameterMap function:

parameterMap: function (options) {

return JSON.stringify(options);

}

This creates JSON in the Request Payload:

{"take":5,"skip":0,"page":1,"pageSize":5}

But it seems to me I shouldn't need to override parameterMap if I'm telling the datasource to use application/json.

My only guess is that Kendo is just passing the contentType to the internal AJAX call to set the POST header and not actually doing anything with that information (like converting the URL/form encoded parameters to JSON).

How to bind child elements on the click of parent row in MVC

I want to show a Kendo Treelist on my page without any child elements.
But when I click on any row, an ajax call has to be made to fetch the data and the row should expand with the child elements under it.
How can it be achieved?
