This feature was already requested in another post, but it was missunderstood. (http://kendoui-feedback.telerik.com/forums/127393-kendo-ui-feedback/suggestions/11578722-support-sorting-datasource-groups) The idea is to allow for Groups in DataSources to be sorted in ways other than alphabetically; this will allow for certain groups to be given priority.
"WebAPI now uses the DateTimeOffset time as a main type when it comes to dates. However DateTimeOffet requires the Model(that the dataSource creates) to keep information for both Date and Offset which is not possible with the current architecture of the DataSource and Model of Kendo." Based on http://docs.telerik.com/kendo-ui/aspnet-mvc/helpers/grid/how-to/oData-v4-web-api-controller Please add full support, also when working with Dates. Thanks.
Add sort/filter events or add an extra parameter in the 'change' event object so that we can detect if a data source was filtered or it was sorted.(Mostly needed when working with grids)
Wish to have a "reset" or "clear" method to restore a DataSource object to it's initial unpopulated state--specifically when used behind a search text box, and need to clear the datasource when the user removes all search text.
The DataSource API currently includes the methods pushCreate, pushDestroy, and pushUpdate. These methods roughly correspond to add, remove, and set. Unfortunately there is no pushInsert to enable adding new items to the data source at a specific position. Adding such a method would be consistent with the existing add/remove/insert methods.
Possibility to add filters to hierarchical datasource, that execute recursively. Use case: In TreeView we need to search for some element text, we need to see elements that contain some text and their parents expanded. Filtering could be usefull here.
One should be able to group by a specified field, and then sort the groups themselves NOT by that field but by another field. For instance, it is currently not possible to sort data by its name but order it by its date.
In order to clearly identify if a datasource operation is successful, two alternatives are possible: 1. Add success event to the datasource in order to get datasource operations separated from update, destroy, add. 2. Enhance change event by error array. Currently, the change even is fired even in case of an error. So, at least an error array containing error messages should be available, together with a property "hasErrors".
Though KendoUI already has an MVVM style binding, it would be much better to have a css binding allowing us to set class on HTML elements based on arbitrary conditions. Just look at the Knockoutjs css binding.
Add a visible property to the column items for the grid control. Then provide the value in the view-model. This would allow us to declare the columns in html and manage their visibility in the business logic.
signalR gives the possibility to quasi direct connection to the server side with easy parameter passing and easy implementation.
Add support for automatic polling/refresh on DataSource. Property: interval in milliseconds
Option to refresh one item from a datasource from the server using a GET request using the transport read url appended with the item ID field value. See: http://www.kendoui.com//forums/framework/data-source/how-to-refresh-an-item-in-a-datasource-with-server-data.aspx
I am creating a realestate website, I want my url to be readable, For example my site url is http://sitename/property/3, (3 represents property id) I want to change it like this link www.paarthrepubliclucknow.in Of course they are using id and all. How can I replace "property" with something like "residential-property-in-india" in my url and it should be changing dynamically according to search. I hope it is clear what I want to do...
There has been many scenarios where I've needed to know when a DataSource finishes a "read" or "sync" operation. I know there's the global "sync" event that I can bind to, but a lot of the time I only care about the result of one specific sync call. I can use the "one" method to only listen to it once, but this complicates things when I also care about errors. Since I need to register callbacks for both the "sync" and "error" events, and then unregister either one or the other, depending on which event fired. It's even harder hooking into a "read" event because the DataSource doesn't expose one. I know I can hook into the "change" event of the DataSource, but I still have to guess whether the change event was fired because of read, or because of some other change. If these methods returned a deferred it would be a lot easier to handle the circumstances where an app needs to do additional things after a "read" or "sync" is completed.
Mobile app should be able to save the data locally in the mobile device and when online network status is detected, should have the mechanism to synchronize the local data back to the server. I asked this during the webcast demo about supporting the html5 local web storage or the html5 indexeddb.
I know you're continuing to improve the kendo/angular integration, but with the rise of full single page applciationsI think you need a deeper integration between the data source and the use of $http (ie services or resources), to cater for such things as custom http headers (for authentication/authorization, application state, etc), which are often set using http interceptors. A typical example is an authentication token. I'd rather use the grid & data sources' built in functionality such as just setting the url for the source of the data, but this doesn't allow any way to set custom http headers to have the auth token sent along with the request. I see two options: 1. Allow the dataSource to use $http directly for its transport, thereby piggy-backing ontop of the angular http architecture. 2. Keep what you have and allow the requestStart event to have access to the HTTP Headers collection, thus allowing us to modify them before the request gets sent.
