Hi Thomas,

1. You could make a DelegateCommand in ViewModel and bind it to "TableView" SelectedCommandProperty. ex: this.AddBinding("TableView", BindableProperties.SelectedCommandProperty, "SelectCommand");

2. You could try set InteractionMode to ChoiceInput and ChoiceInputMode to Multiple.

3. I have test MyInventory sample with Item data down to 5. The result show there is no empty rows. Please tell me the step-by-step used to produce the issue and provide me with a sample if possible.

4. It's possible to set a label with multiple lines text. After you set the multi line text, you need to specify the number of lines that will use to render the text. It will look like the following code:
label.Text = "Line1\nLine2"
label.Lines = 2;

Hope this useful.

Best Regards,
Leo

Hello Leo,

Thanks for your response.

Points 1 and 4 work like you described it. But regarding point 1 I wonder why "RowSelected" or "RowHighlighted" never get called within the ViewController. Are these "Events" suppressed by Crosslight? The same with "OnSelectedItemChanged within the ViewModel. It is not called when changing the selection of the TableView. This seems like a bug to me. By the way, I use the iOS unified assemblies.

Your proposed solution for 2 is not an option for me, because I don't want to have the "checked" icon when a row is selected. Is there another possibility to deselect a selected row? I tried "this.SelectedItem = null;" but it didn't work.

I have attached a screenshot to describe point 3 better. Here the tableview has 4 rows with content, but there are much more row separators shown.

Thanks,

Thomas

Hi Thomas,

Thanks for your information.
I have look into the empty row behaviour that you have mentioned. It is the default behaviour on iOS. But you could change this behaviour by changing Appearance property that is already defined. Please add the following code to your view controller:

public override TableViewAppearance Appearance {	get {
		var appearence = new TableViewAppearance ();
		appearence.HideSeparatorOnEmptyCell = true;
		return appearence;
	}
}

As an alternative, you could simple change the appearance on InitializeView.

Regarding deselecting a selected row, it is a non-standard behaviour except for multiple selection. But still, you could easily implement this behaviour on view controller OnViewModelPropertyChanged. That should give a control to what to do in view controller when there is a changes to it's viewmodel property. The following a snipet code about how you deselect a selected row after it is clicked:

BindingProvider :

this.AddBinding("TableView", BindableProperties.SelectedItemProperty, "SelectedItem", BindingMode.TwoWay);

ViewModel :

public override Item SelectedItem {
	get {
		return base.SelectedItem;
	}
	set {
		if (base.SelectedItem == value)
			base.SelectedItem = null;
		else
			base.SelectedItem = value;
	}
}

ViewController

protected override void OnViewModelPropertyChanged(System.ComponentModel.PropertyChangedEventArgs e)
{
	if (e.PropertyName == "SelectedItem") {
		if (this.ViewModel.SelectedItem == null) {
			TableView.DeselectRow (TableView.IndexPathForSelectedRow, true);
		}
	}
}

public override TableViewInteraction InteractionMode
{
	get
	{
		return TableViewInteraction.Standard;
	}
}

Hello Leo,

your proposed solutions work great.

Thanks,
Thomas

Hello Leo,

any news about "RowSelected" or "RowHighlighted" from the developer team?

Thanks,

Thomas

Hi Thomas,

Sorry for the delay. From the answer I got from our developer team, The event was suppressed by crosslight because all logic operation should be done in ViewModel.

Edit : Hotfix Link has been fixed.

Hello Leo,

Thank you for the update. Unfortunately, I cannot access the hotfix link. Following "this link" mentoined above, I come to a login page. My regular Intersoft account login does not work here. So, I cannot download the hotfix.

Do you mean "Crosslight4_0_5000_303.zip" with the hotfix? I just downloaded this version from the git repository.

Thanks for clarifying.

Thomas

Hi Thomas,

Sorry about the link, I have fixed that. Now the link should have pointed to Crosslight4_0_5000_303 hotfix that you have downloaded.

Best Regards,
Leo
