I have a working asmx web service, which returns JSON data, feeding a grid via a datasource:-

This works fine.  However , when I try to pass a parameter to the asmx service (to enable server side filtering), like this:-

I get an Invalid JSON primitive error.  Using fiddler, I can see that the call to the web service is http://localhost:51465/WidgetService.asmx/GetPatientsFiltered?srchFilter=blue&take=10&skip=0&page=1&pageSize=10
, but as it's a JSON call, it isn't encoded correctly. How can I correctly format the call?
Also, even though server side paging is set to false, it's passing the paging parameters - the only way to stop this is to remove the pageSize setting, which then removes client-side paging on the grid.  How can I fix this.

It would be really helpful to have a lot fuller documentation on the datasource, including all the options and parameters that can be used, and the sort of services it is expecting (i.e. parameter names / formatting etc..). Currently I feel as if I'm stumbling around in the dark (and most examples on the web either relate specifically to jquery, or asp.net AJAX).

Thanks

Hi,
How I can create i validator message with tooltip ?

Thanks

I'm using jquery mobile with some controls of kendo ui (either kendo mobile isn't out yet).

Jquery Mobile use AJAX to load the content of the next page and replaces the content of the div with the attribute data-role="page". 
This is fine and works great, but with the time the page gets slower and slower. the reason for this is, that kendo ui creates elements in the body of the document, and those elements are never removed... so the page dom increases with every page load... 

Is there a reason to destroy existing controls so that they remove the generated content in the body? Or can I define in which element kendo ui will generate the hidden divs?

Thank you 
Micha

When I try to scroll an opened dropdownlist on the iPad, it selects the item that was touched in the list and then closes. So to select the actual item that I'm looking for I have to open and scroll n number of times until I reach such item.  Is there a way to differentiate the touch between a drag and a click.  I was thinking about trying to make it cancel the close when the drag event happens.

How can we add data to the HTML headers sent by the data source?
Is there a function or property that will do this?

Something like this would be a simple fix as JQuery 1.5.* supports adding
a "headers" map to add any custom headers you want.

                        transport: {
                            read: "http://localhost/WebAPITest/api/Transactions",
                            datatype: "json",
                            headers: { Authorization: "user/password" }
                        },

Thanks

Hello,

Can you provide several examples for MVVM with TreeView and a JSON DataSource ?

Hello

Items CAN USE Kendo in functions

sample :

this.ComboBox = this.kendoComboBox();
this.ComboBox.setName("COMBOID");
this.ComboBox.setWidth(550);
this.ComboBox.setHeight(33);
this.ComboBox.setIndex(0);
this.ComboBox.setdataTextField("Name");
this.ComboBox.setdataValueField("ID");
this.ComboBox.setFilter("Contains");
this.ComboBox.setDataType("odata");
this.ComboBox.setserverFiltering("true");
this.ComboBox.setServerPaging("true");
this.ComboBox.setPageSize("20");

would generate the following results will :

$("#comboBox").kendoComboBox({       
index: 0,       
dataTextField: "Name",       
dataValueField: "Id",       
filter: "contains",       
dataSource: {           
type: "odata",           
serverFiltering: true,           
serverPaging: true,           
pageSize: 20,           
transport: {               
read: "http://odata.netflix.com/Catalog/Titles"            }        }    });


thanks.

What is the easiest way to dynamically insert html content into a kendo PanelBar?  For example I would like to place checkboxes next to item titles.  Is there a flag like 'encoded' for the Treeview? 

I have a suggestion that would simplify the way to retrieve specific cell values from data items when selecting multiple rows from a grid.

Right now, the only clean way to get cell values from selected rows would be to get the selected elements with grid.select(), then go through all the rows and then build your own array with the desired cell values.

Why not implement something like this:

var usernames_and_emails = grid.dataItems(grid.select(), ["username", "email"]);

The usernames_and_emails variable would contain all the selected rows as javascript objects, each object having the username and email properties.
If the second parameter is omitted for the .dataItems() method, then it should get all the columns for the grid.

Also, it would be nice to have a method to get a single column instead of an array of objects

for example

var user_ids = grid.dataItemsColumn(grid.select(), "id");

user_ids would be an array with ids.

I think this way it would be a bit easier to fetch data when working with multiple rows.

---------------------
Long story short

dataItems (tr_array  [, fields_array])
returns an array of data items for the specified tr elements in the "tr_array"
if the "fields_array" is specified, only the fields specified in the array are returned

dataItemsColumn(tr_array, field_name);
returns an array of cell values (indicated by "field_name") for the specified tr elements in the "tr_array"

I guess this would eliminate the use of writing some repetitive code or implementing a custom function.
