Currently, the spatial types (geometry and geography) is not supported in LightSwitch. I would like to show customer location on the map or calculate distance.

It would be very useful if we could format the cells in a column of a grid with a percent format, currency format, or decimal format, just like we do in Excel. Simple and effective, just selecting the column and press the "percent" button and all the cells in that column has percent format.

First impression of Lightswitch...what a fantastic product for building LOB applications but the limited screen, UI and menu formatting results in applications that look amateurish. I'd like to be able to control colours and fonts. The main weakness is the menu/navigation bar on the left. It could do with a standard theme to make it look and work like Outlook. You need to be able to add an icon to menu items and control colour, separator and so on. In a line-of-business application, look-and-feel and ease of use are very very important to users.

Modify the entity designer to use the relationship name as the column name in the database table rather than your generated name which makes no sense when you are writing queries outside of lightswitch.

many users want to use keyboard Function like F10,F5 to save data or to enter new records also other want to use Enter Key to move between fields on screen

When a new OOB app version is published, instead of showing some sort of a progress like a percentage counting or something window contents are blank and only after it gets updated it shows a message that it is completed. This is very disturbing, since you can not know what is happening during this period and it looks like the application got stuck.

When I enter a text in the Search box for a screen and do an update on one of the filtered fields let's say in a grid box, after the Save operation and screen refresh, the selection is gone.
I think that it would be great if the screen could remember the selection and filter parameter and bring the grid to the same page and record (same like Internet Explorer remembers the page and the position on the page), otherwise I need to re-enter the search parameter and scroll again to the page 20 etc... Thank you

Customers have become accustomed to being able to double click on a grid entry to perform a default action. This however is not supported natively in LightSwitch. Consider adding double click functionality to allow an action to be initiated.

Please add the possibility to import data from excel sheet. Please notice this control already exist.

Export information; please notice the export to Excel sheet only export data per data grid view page. Sample if you have 3 pages of grid view data; only the page you are in gets exported.
The export to Excel sheet control should have a possibility to select from and to page, and row number from and to. We need more possibilities to control the export to Excel sheet.

Ability to create a WebService (ASMX).
This could make it possible to interact with the LightSwitch Data from other Applications.

ASMX is the old fasion way. A WCF Service with Methods or maybe ODATA access could also fit.

This is much better then an seperate solution because you can use the same security implementation and the deployment makes less problems.

Multi-select is such a generic feature in LOB system, currently, the recommended workaround is to add a bool checkbox column for table which needs to support multi-selection, ugly.

At the moment, a seemingly simple thing that Clients ask for is not a straight forward to implement in LightSwitch. There still is no clear cut way to implement this that works with paging and sorting.

I'm a programmer. Whilest I can use the "Write Code" dropdown to insert code blocks into the Application, ApplicationDataService, EntityObject<T> and ScreenObject<T> classes, I would like the ability to define entites, screens, relationships and queries through code / markup / a DSL.

Obviously Lightswitch meta-programs this when I use the designer, but I would lke to do it myself.
Expose the DSL - so that it is possible to build a Lightswitch App without using the designer

Allow the placement of Totals - above or below the grid/list/etc. Page Totals? Auto alignment of Totals to Regular Column Totals.

Add a default sorting property for each entity. This property will then be used by LS when creating auto-complet box using the entity as a source and in all list as the default sort order.

This could be done in previous version of LS by adding code to the <entity>_all_PreprocessQuery(), but this method is no longer available in VS2012.

This forces us to replace all automatically generated modal edit form by our own just to set the order in the Auto-completed boxes they contains.
