Latest Microsoft Visual Studio LightSwitch Forum Threads That Have Answers

Hi all, I have tried to use the itgLsEnhancedTable with one database table (filter on query), one screen and two tabs, but I am struggling to get the filter working. I am able to filter the data, but when I hit the "Clear All" button, the result will none, not even "No Items" will appear. I am using the suggested code below to save the old query and filter (replaced the old one)   query = options.contentItem.details._entry.simpleDescriptor.createQuery; //only override once – have we done this already? if (!query.old) { //save the old query options.contentItem.details._entry.simpleDescriptor.createQuery.old = query; //override the query options.contentItem.details._entry.simpleDescriptor.createQuery = function () { return query.old.apply(this, arguments) .filter(properties.filterString)

Hi, I need help with getting the row number out of collection. My example is as follows: I have one master record with assigned 6 details. For example if i have 6 details (boxes), i want to select one box (lets say third box) and print a sticker for box 3/6. How can i get number which row is selected?

I am coming across a problem that in my mind should be easy, but is not going like I want. I have a many to many relationship set up between Customers and Hardwares tables --Many customers can have many hardwares. I have a query set up with a parameter called CustomerId that filters the Hardwares collection by Customer by looking at the middle table CustomerHardwaresCollection. This query runs like I want. query = From h In query From ch In h.CustomersHardwaresCollection Where ch.Customer.Id = CustomerId.Value Select h My problem occurs when I attempt to do the opposite. I want to filter the hardwares list excluding any hardwares already matched to a customer. 
query = From h In query
        From ch In h.CustomersHardwaresCollection
        Where ch.Customer.Id <> CustomerId.Value
        Select h
So I try to query where the values are not equal, but I wind up with an empty query when I know there is data there
