Currently, I have a list view that allows items within the list view to be dismissable. I want each item within that list view to correspond to an element within another list that contains text. And when that widget in the listview is dismissed, then the corresponding element in the other list also gets deleted. Does anyone know hot
What I suggest is that if there is any common thing in both list that are related to each other such as id or any else say text in your case ,After dismissible widget get triggered iterate via the second list just check if there's any common based on the 1st list item, and delete the item rebuild the state. Maybe adding some code might be better but so far this is the best way you can do. let me know if it work.

Is there a way to populate a List property on an object being tested under the "new style" test scenario?
I see some "legacy" test cases which seem to achieve this so am wondering if the new style test scenario handles this.
I added the List model to my test case, which enabled me to expand the sub-property on the object, however there is only one field available there, "empty" (boolean). Is there a way to add an object here? If it makes any difference, the model is an external java dependency.
Update
The reason I wasn't able to add the List of objects was because I didn't explicitly import that object dependency into the test. Once you import it you can follow the steps given in the answer below.
It's definitely possible to manage a List property under the Test Scenario Editor.
Please consider the following example: A Book class with a List<String> property named topics.
Creating a new Test Scenario assets, please select the column where you need to add the List property, and in the right part of the editor select the property expanding the Book class, as shown below:
Pressing Insert Data Ojbect button will assign the selected List property to the selected column:
To fill the data in the List property, please double click on the Insert value cell, in the first scenario data row. A popup will appear. Its aim is to fill data inside a collection
To add a value, please press the Add list value link in the bottom part of the popup. Here, you'll be able to fill a single item on the list
Repeat this step for all the items you need to add to the list. When completed, simply press to Save button
The popup will close and you should see the previously selected data cell filled with a label similar to List(2), the number represents the number of the items in the list.
I was trying to make an app in flutter, I now have an app that adds a new element into a list upon pressing a FAB. Kindly let me know how can I map another ListViewBuilder to each element. I am not sure if I am being clear enough, but I am trying to be clearer. I want an app that lets you create lists inside of lists, in flutter. So for each List element, there lies a corresponding list in which the contents of the list can be added. I am a beginner, and I am struggling to figure it out. plzzz, help me out..thanks in advance...
To create a list in a list you can use:
List<List<int>> numbers = new List<List<int>>();
And then you can add a new list to this by doing:
numbers.add([0,1,2]);
This adds the list [0,1,2] to the list called numbers.
From here you can access an element in this case the second element in the first list:
x = numbers[0][1]
i've a question to ask for my mvc project...
i have two controllers: Giurisprudenza e GiurisprudenzaNode, these controllers implement an index with the list of elements and a crud system to add/edit/remove elements. In the Girusiprudenza view page every element has a button that return you into the relative GiurisprudenzaNode page, with the list of elements contained into the primary element.
I would like to insert a label next to every element of the list in Giurisprudenza that say how many elements there are into that single primary element, but i don't know how to do that count... Anybody can help me?
for this you dont need two controllers or two different view .
For this you need to follow below steps.
Create a viewModel (Customize mix of both models)
add custom property in you this viewmodel for counts
create new view for this ViewModel class .
Let me know if you need code snippet for this.
View Model from MSDN
I am trying to dynamically modify the items in a List (ObservableCollection) of a ViewModel and have those changes get updated in the View via MvvmCross bindings. My eventual goal is that when a user clicks on a list item, I will pop up a dialog asking them to edit that item. When the dialog is dimissed, the viewmodel will get updated (through an ICommand I assume) and that modified value will be now be in the list.
I haven't looked into dialogs yet, so for now I am just trying to toggle a boolean value each time a list item is clicked and have that value changed in the MvxListView. I have the MxvListView in my View bound to an ObservableCollection in my ViewModel and have an MvxCommand that is getting called when an item is selected. All this is working and I can see the value getting changed in the debugger, however, the new values are not being displayed in the MvxListView. So my question is: How do I get modified data in individual items in an ObservableCollection to bind to an MvxListView?
All of the examples I have seen online use ObservableCollection for dynamic binding but they only ever Add or Delete items. I haven't found any examples of modifying the items. If I change the code in my MvxCommand from modifying the data to adding or deleting an item, the list will get updated. So that tells me I'm close I think.
Rather than copy paste the code in here, I created a sample project on github here to look at:
https://github.com/smulrich/breaktimer
I appreciate the help.
You can simply replace
Breaks[index] = b;
with
Breaks[index] = new DailyBreak() { Reason = b.Reason, TimeOfDay = b.TimeOfDay, Enabled = b.Enabled };
or more reasonable, you should realize INotifyPropertyChanged for class DailyBreak

I have an list of checkboxes on a GWT widget using Gwittir. I want to bind these checkbox values in my view to some values in my Model so that I can tell which ones are selected. How can I set up a binding to do this?
For a single value (one not in an array), I've been doing this:
Binding binding = new Binding();
binding.getChildren().add(
new Binding(viewObj.getTextBox(),"value",modelObj,"textValue"));
But I don't know how to transition this to work for an array of items. Please help.
I ended up not using Gwittir for those parts which dealt with arrays of data. Instead I manually transferred the data from my view to my controller when the user clicked a button which would record the state of all the checkboxes in an array to an array of values in the controller.
