Local data storage

[Eddie Conner]

Are there any options for local data storage to a database like SQLite? I am looking to build an application that can run offline as well.

Hi Eddie Conner,

Unfortunately, we do not provide out-of-the-box binding to SQLite.
Could you provide a bit more details about your scenario and which database you will target?

I am looking at having to develop an iPad and maybe droid and windows tablet application. I need to be able to work with the application offline and save data to a local database. Then I will need to connect to the internet and sync data to via WCF/RIA services. I also need the data to be stored securely and encrypted due to the data is personal information. The data needs to be encrypted with AES256 support.

Also I need to be able to display a report from the tablet showing results of the data. Today I can do that with Telerik Reporting from my desktop application. How can this be handled with KendoUI?

Hi Eddie Conner,

Thanks for your feedback and the additional details. We currently do not provide a reporting viewer with Kendo UI.

I'm having the same question. 

I would like to use Kendo UI Mobile and PhoneGap to develop an Android/iOS phone app that stores approximately 8MB text data locally. The local data will be sync with a clould server via WCF.

I don't need to manipulate the local data much but I would like to be able to search and sort it quickly. Also, I would like to start / load the app quickly.

What is the best option for the storage in this case?

Hello George,

We do not provide such built-in implementation for our DataSource component. However, you may consider using a custom transport by implementing the read (and if required by your scenario create/update/destroy) method. Here you can find an example of how to use websql database and custom transport.

Does Kendo Datasource supports encryption ?

Hello Sweta,

I am afraid Kendo UI does not include a built-in encryption mechanism.

Normally developers would resort to HTTPS for data transfer security. However, if your goal is to benefit from client-side encryption, so that a third-party cloud storage service has no access to your data, then I can suggest the following approach:

- choose a third-party client-side encryption tool

- decrypt the data received from the server in the DataSource's schema.parse function.
https://docs.telerik.com/kendo-ui/api/javascript/data/datasource/configuration/schema#schema.parse

- encrypt the data to be sent to the server in the DataSource's transport.parameterMap function.
https://docs.telerik.com/kendo-ui/api/javascript/data/datasource/configuration/transport.parametermap

We have a feature request for built-in encryption on our feedback portal, but it has not gained much popularity yet:

You can consider upvoting the request, as we take into account the most wanted features when planning our roadmaps.
