问题 I deployed a desktop lightswitch application and my users are getting this error when they install the application: Strong name signature not valid for this assembly Microsoft.LightSwitch.Model.Xaml.dll This error is causing the install to fail.

Lightswitch: parameter with string and integer searching properties (is it possible?)

阅读更多关于 Lightswitch: parameter with string and integer searching properties (is it possible?)

问题 Just a quick question within the HTML Client side of Visual Studio 2013 Lightswitch, is it possible to set a parameter field based from a query to allow both sting and interger values to be searched... an example would be StaffID(int) and StaffName(string)... cheers guys 回答1: Sure - just add a .ToString() when you present on your int to the search query argument if Javascript isn't doing the conversion implicitly. e.g. searchString = intField.ToString() + ((intField==null)?" ";"") + strField

Lightswitch HTML - disabling the CTRL + S functionality

阅读更多关于 Lightswitch HTML - disabling the CTRL + S functionality

问题 It turns out then when you have an Add/Edit screen open (dialog or full), that you can hit CTRL + S to save the screen. This avoids all validation I have coded, and also does not matter if I have disabled Lightswitch's own save button. How can I disable this? on a browse or view screen, this does not occur and the user is only able to save there web page 回答1: One option to disable the Ctrl + S is to remove the msls-save-button css class from your screen's save button. This can be done in your

问题 I installed VS2012 and tried to open a project that was developed using VS2012 as well by another developer. But I am getting an error message as below.

The original developer said it is a Light Switch and Entity Framework project. How can I start trouble shooting to find out what I am missing on my computer and to solve this problem? 回答1: The error message

阅读更多关于 OData Default company and adjusting Service Config Files in Silverlight App being built in MS Visual Studio 2013

问题 I'm building a Lightswitch application using MS Visual Studio 2013. As part of this I access data through an OData url (referencing a dynamics nav project) which does not seem to want to pick up the company data in the url. (It does without it). However then within Visual Studio I only see the column headers and no data. When I debug I get the following error message: "Cannot process the request because the default Microsoft Dynamics NAV company cannot be found. You can specify a default

LightSwitch and Expression Blend - Will they work together?

阅读更多关于 LightSwitch and Expression Blend - Will they work together?

问题 how well can LightSwitch work together with Blend? I saw in some videos that you can use custom Silverlight control in LS and naturally I can create them with Blend. But can Blend in itself be used to customize the screens of a LightSwitch application? It seems LS doesn't use Xaml but puts all screen in an application.lsml file which is invalid for Blend. Is there support coming here? Thanks in advance. 回答1: No. You will never be able to customize the LightSwitch 'Screens' in Blend, because

How do I get MS LightSwitch to recognize my View?

阅读更多关于 How do I get MS LightSwitch to recognize my View?

I've created a View from a table in another database. I have dbo rights to the databases so viewing and updating is not a problem. This particular View did not have an "id" column. So I added one to the View by using ROW_NUMBER. Now I had a problem with a table, in the same database, not showing up in LightSwitch but that was solved by changing the id column to be NOT NULL. I haven't done any real manipulation in LightSwitch. I'm still in the Import Your Data Source stage (ie. very beginning). This View, in LightSwitch, is going to be read-only. No updating or deleting. From what I've read,
