B4J Library [BANano] Kendo UI Core - Wrapper

Hello,

i would like to present my first version of a BANano wrapper for Kendo UI Core.

You can see a demo version here: http://banano.tuebben.de/kendoui/demo/

What is Kendo UI Core?

Kendo UI is a library that provides some powerful and nicely designed controls. Besides the paid full version there is a free core version which does not include some controls (like the grid, scheduler, charts, etc.).

Here is an overview of the available controls in the core version: https://github.com/telerik/kendo-ui-core

Please note:

Currently the wrapper has the status of a 'proof of concept'.
Not all controls have been implemented yet.
And the already implemented controls do not yet support all properties and methods.
The documentation still needs some work.

For this reason only the brave and fearless would be able to work with the library at the moment. ;)

If you are interested, I can publish the library and a demo code.

Greetings ... Peter

// Edit (03.03.2019 16:00): I have now added the required files to this posting.

Quick installation guide:
  1. Extract the files in Library.zip into the Additional Files folder.
  2. Extract the files in BANanoKendoUIDemo.zip into a folder of your choice and start B4J with BANanoKendoUIDemo.b4j.
  3. Adjust the path in BANano.Build() according to your needs.
// Edit (14.03.2019 15:45): The library has been updated to version 0.14

@GanjaKyp : Please try again with the attached files.

At least SimpleDemo should work.

Impressive work !

A question: would be possible to use the kendo library also only in conjunction with ABMaterial ? Or do I need BANano for that ?

Sergio

Tutorial: BANanoKendoDataSource (Part 2) (you can find part 1 of this tutorial here)

We start with again this code:
B4X:
Dim myDataSource As BANanoKendoDataSource
myDataSource.Initialize(Me, "myDataSource")

myDataSource.Add(CreateMap("name": "Jane Doe", "age": "30"))
myDataSource.Add(CreateMap("name": "John Doe", "age": "33"))
myDataSource.Add(CreateMap("name": "Jill Doe", "age": "55"))
myDataSource.Add(CreateMap("name": "Jock Doe", "age": "99"))

Dim myListbox As BANanoKendoListbox
myListbox.Initialize(Me, "myListBox", "myListBox")
myListbox.AddToParent("body")
myListbox.DataSource = myDataSource
myListbox.Template = "#:name# is #:age# years old"

... to get this Listbox:

Z4lseC3.png


Filtering items:

KendoDataSource can filter data entries according to certain criteria.

For example:

B4X:
' Return all records whose first name begins with "Jo":
Dim myFilter As Map = CreateMap("field": "name", "operator": "startswith", "value": "Jo")
myDataSource.Filter = myFilter

sroHZCI.png



B4X:
' Return all records whose age is greater than 50 years:
Dim myFilter As Map = CreateMap("field": "age", "operator": "gt", "value": "50")
myDataSource.Filter = myFilter

M1QzFEG.png


The following values can be entered in operator:
B4X:
"eq" (equal to)
"neq" (not equal to)
"isnull" (is equal to null)
"isnotnull" (is not equal to null)
"lt" (less than)
"lte" (less than or equal to)
"gt" (greater than)
"gte" (greater than or equal to)
"startswith"
"doesnotstartwith"
"endswith"
"doesnotendwith"
"contains"
"doesnotcontain"
"isempty"
"isnotempty"


You can set several filters as a conjunction (AND):

B4X:
Dim myFilter As Map
myFilter.Initialize
myFilter.Put("logic", "and")

Dim myFilters As List
myFilters.Add(CreateMap("field": "name", "operator": "startswith", "value": "Jo"))
myFilters.Add(CreateMap("field": "age", "operator": "gt", "value": "50"))

myFilter.Put("filters", myFilters)  

myDataSource.Filter = myFilter

RKn0oQQ.png


... or OR:

B4X:
Dim myFilter As Map
myFilter.Initialize
myFilter.Put("logic", "or")

Dim myFilters As List
myFilters.Add(CreateMap("field": "name", "operator": "startswith", "value": "Jo"))
myFilters.Add(CreateMap("field": "age", "operator": "gt", "value": "50"))

myFilter.Put("filters", myFilters)  

myDataSource.Filter = myFilter

That's it for now. See you later at the next tutorial. :)

Tutorial: BANanoKendoDataSource (Part 3)

KendoDataSource also has the ability to aggregate data.

Again, we take the Doe family as an example:
B4X:
Dim myDataSource As BANanoKendoDataSource
myDataSource.Initialize(Me, "myDataSource")

myDataSource.Add(CreateMap("name": "Jane Doe", "age": 30))
myDataSource.Add(CreateMap("name": "John Doe", "age": 33))
myDataSource.Add(CreateMap("name": "Jill Doe", "age": 55))
myDataSource.Add(CreateMap("name": "Jock Doe", "age": 99))
(please note that in contrast to the previous examples, the age is passed as a number here)

Now we want to know who is the youngest (min) and oldest (max) family member and the average age of the family:
B4X:
Dim myAggregateList As List
myAggregateList.Initialize

myAggregateList.Add(CreateMap("field": "age", "aggregate": "average"))
myAggregateList.Add(CreateMap("field": "age", "aggregate": "min"))
myAggregateList.Add(CreateMap("field": "age", "aggregate": "max"))

myDataSource.Aggregate = myAggregateList

The possible values for the aggregate-field are:
B4X:
"average" - Only for Number.
"count" - String, Number and Date.
"max" - Number and Date.
"min" - Number and Date.
"sum" - Only for Number.


With the Aggregates-function we get a map whose members we can read out:
B4X:
Dim ageAggregate As Map = myDataSource.Aggregates("age")

Log(ageAggregate.Get("average")) ' -> 54.25
Log(ageAggregate.Get("min")) ' -> 30
Log(ageAggregate.Get("max")) ' -> 99

That's it for now. See you later at the next tutorial. :)

Greetings ... Peter

Thanks @Kiffi Problem solved moving librarys to Additional Librarys folder.

Now, I have a question...
I was added two TextFields and two Buttons to WindowLayot (on BABanoKendo demo) to simulate a Login and Register new users on a MySQL database (based on this sample https://www.b4x.com/android/forum/threads/banano-mysql-crud-with-php-part-1.104622/).
How I can get the TextField values (name and password) and send to my database (making a call to php process) when I click the button ?

Thanks a lot, regards
