I previously used the Telerik MVC combobox control so that it only returns results when at least 3 characters have been entered. I was able to specify this in my controller by simple checking the text string that was passed in the ajax request.
With the KendoUI combobox, I cannot figure out how the text is being passed and what to check for in my controller to see if at least 3 characters have been entered.
Can you provide any assistance with this? Thanks.
UPDATE:
So I found by looking at the AutoComplete control, that I can set the ComboBox to not retrieve results until at least 3 characters are entered by using minLength: 3
I still have the issue on the controller side, however, that I don't want to bring back the entire list...I only want to bring back results that contain the text entered. What do I need to include on the controller side to get the text entered in the ComboBox?
Thanks!

Hi,
I'm loading the content of a window by using the refresh method with a URL. Is there a way to find out which URL the content was really fetched from (if it is redirected)?
I know that I could just check the content and look for some unique element to discern which page was loaded if I know the content, but this is not always feasible.

Hi,
A seconde question about the DataSource is how can we get the Data of a subset into f.i. a grid. Here's the code we use for our JSON services.
The consumed class VMRoot looks like this:
The VMEntitySet is an ObservableCollection which contains VMProjectRegel objects. These are defined like so:
The JSON we receive looks like this:
The DataSource is defined like so:
after executing the dataSourceprojecten.read() the data is available for the main list but how do we specify the fetch for the ProjectRegelsList in f.i. a grid?
This is what I have tried (among many other attempts) to get it to work:
Regards
Paul

I try to make a single page web app. It will contain some grids and forms. Some of the form controls and grids are based on the same datasource. Sometimes I need to get a specific item from the datasource (identified by a parameter) or sometimes I just need every available item from the datasource.
I've solved this problem by adding a parameterMap to the transport of the datasource. Now I'm able to exactly retrieve all items from the datasource, how and when I want. For code example, see rootDatasource below.
In the widgets which I'm using, like Grid, I want to call the read method of the datasource with a parameter specified to retrieve all items from the back-end which match the query 'active' == true. See code example:
And now my problem, this won' work!! I'm really confused, if I just add a reference to the datasource object without directly specifying the .read() method, it just works. (Retrieving all items, including 'active' == false though.) In another form I want to specify some other parameters, so just adding the parameters to my (PHP) back-end just doesn't work.
I've been reading the docs en forums quite extensively to find an answer, didn't find it and I find myself quite stuck right now. Any help will be much welcome.

I'm trying to validate a <textarea>. Is it even possible to validate any other fields beside inputs? The documentation (http://docs.kendoui.com/api/framework/validator neither http://docs.kendoui.com/getting-started/framework/validator/overview) does not say anything about this.
If <textarea> is not support, how can I achieve validation of multiline text inputs with <input>?
Thx!
Henning

Hi,
Can we have range selection ability within DatePicker's calendar. Like i have two datepicker controls i.e., Startdate and Enddate. Both datepickers control will be populated with StartDate's Calender selection. For this I have to make 2 clicks on StartDate's calender for selecting range. Currently, datapicker's calender is closed after having one click so range selection is not possible. Please suggest.

I would like to know how different is to use full source code (for debugging purposes) of Kendo UI MVC wrapper extensions.
So instead of minimized files I would like to deal with full version of .js, .css files and I would like to peek into HTML helper's source code.
Any article/documentation on how to do that. I would like to first try a test solution with a trial version and to understand how it would be different if I would reference source project of MVC wrappers and uncompressed content and script files.
Thanks,
Rad
