Hello friend, I am developing a XAML title to display percentages via JSON datasource. It is already loading data normally. However, the number of lines can sometimes vary, so there is no way I can leave a fixed number of results. What is the best way to repeat the lines, or hide the empty ones? I tried using the xaml converter, however vMix did not accept it. I made a script to see if the name field is empty, if it was, it hid the grid of the whole line. The way I put it to repeat the fields in vMix was to select the column and then what line number will be displayed. Thankful friends.

Is this a question or stating that you found a solution ? Quote: I made a script to see if the name field is empty, if it was, it hid the grid of the whole line.

Is a question. I said that I tried to do this but vMix didn't accept it. Compiling within Visual Studio worked, but not within vMix. So I ask if I am on the right path or if someone has another solution? Originally Posted by: doggy  Is this a question or stating that you found a solution ?

Yes. The problem is that I put the VB.Net script inside ".xaml.vb" and referenced it using the "xmlns: local" attribute. Then vMix didn't accept it. Where did I go wrong? When compiling the code in Blend everything works. My UserControl tag: Quote:<UserControl x:Class="TelaPrefeito"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

xmlns:mtl="clr-namespace:vMixTitleLibrary;assembly=vMixTitleLibrary"
xmlns:local="clr-namespace:ProjApuracao2020"
mc:Ignorable="d"
d:DesignHeight="1080" d:DesignWidth="1920"> Where to use the Convert function to hide the line with empty text: Quote:<Grid Visibility="{Binding ElementName=TxtNome07, Converter={local:StringNullOrEmptyToVisibilityConverter}}"> The implemented function of IValueConverter: Quote:Public Class StringNullOrEmptyToVisibilityConverter : Inherits System.Windows.Markup.MarkupExtension
Implements IValueConverter
Public Function Convert(value As Object, targetType As Type, parameter As Object, culture As CultureInfo) As Object Implements IValueConverter.Convert
Dim text As String
text = value.Text
Return If(String.IsNullOrEmpty(text), Visibility.Hidden, Visibility.Visible)
End Function
Public Function ConvertBack(value As Object, targetType As Type, parameter As Object, culture As CultureInfo) As Object Implements IValueConverter.ConvertBack
Return Nothing
End Function
Public Overrides Function ProvideValue(serviceProvider As IServiceProvider) As Object
Return Me
End Function
End Class vMix error:  I attached the files. Thank you.  TelaPrefeito.xaml (13kb) downloaded 1 time(s).
