问题 Does anyone know why all dates display in the correct (UK based) dd/MM/yyyy format in Chrome and IE but in Firefox are set to MM/dd/yyyy format? Is there a workaround other than converting every date display to a custom control and using moment.js to render the date into the required format? PC is set to UK location in Control Panel. Thanks 回答1: Having encountered the same issue, and following some rabbit hole exploration in the msls library, we determined that the solution is to ensure the

问题 I having country as Foreign key in one of the table. So it is shown as drop down(is it a drop down? see image above) My question is how can I specify the data in the drop down/input is to be in sorted order? 回答1: As Crezzer mentioned, the foreign key drop down details pickers are intrinsically sorted by entry order (with the earliest records appearing at the top).

问题 I am supposed to find a bug in Lightswitch C# application written in VS2012 which causes application to hung when delete button is clicked. I am new to LS and have problem figuring out how to find the internal code is executed when that button is selected. Even when I try to override action of this button debugger doesn't stop there.

问题 How can I have a where clause in a LightSwitch query against a child collection? In my example, every blog can have many comments and I want to write a query like this so that the admin see only the blog entries without any comments: query = query.Where(q => q.comment.Count() == 0).SingleOrDefault() I've included the SingleOrDefault() because I want the administrator to see only one item per query they can then add a comment and move to next item on the blog screen. When trying the above

问题 I have deployed a lightswitch application that is being used in a production environment. I recently made some changes and need to publish a separate copy installed alongside the original for testing purposes. I tried to look at this video1 on installing click-once applications side by side, but Lightswitch doesn't have the same options that a normal C# application has. I edited the assembly name in the desktop client project but no luck. Any suggestions? 回答1: I'm not sure if this is right,

问题 Dears, If I have a screen and I set the root layout's height to "Stretch to Container" and make sure that no buttons are visible in the footer (So the footer is collapsed), you will notice that the page layout will extend unnecessarily beyond the height of the browser window (causing the scrollbar to appear), and it will extend exactly as much as the header (So if the header is 60px, the extra space at the bottom will be 60px). This looks unprofessional and as footer buttons appear and

Now unlike previous versions i cannot select a file path so i need to write some js via the post-Render section, what do i type in here?

问题 I am using lightswitch and I have a "Grid" with table A. Table A related to Table B and table b related to table C. Now how do I access data from table c using Grid's PreprocessQuery or filter? 回答1: You can expand each relationship in the query designer.

You can filter on any
