I have developed various UserControls in a WPF solution called CustomControls. Once developed, I can copy the 2 xaml files for a control into a new solution ad use it there (or compile into a library, which I'm not presently doing).
Now I'm having a strange problem, and can't figure it out. Here is partial XAML and code-behind for one of the custom controls which is working just fine:
<UserControl x:Class="RonM.CustomCheckBox" x:Name="ccb" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" mc:Ignorable="d" MinHeight="40" MinWidth="20" Height="100" Width="50"><UserControl.Resources>
Namespace RonM Public Class CustomCheckBox Inherits UserControl Implements INotifyPropertyChanged Public Event PropertyChanged(sender As Object, e As System.ComponentModel.PropertyChangedEventArgs) Implements System.ComponentModel.INotifyPropertyChanged.PropertyChanged Private Sub NotifyPropertyChanged(ByVal info As String) RaiseEvent PropertyChanged(Me, New PropertyChangedEventArgs(info)) End Sub Public Sub New() ' This call is required by the designer. InitializeComponent()
Now, I'm trying to add a new UserControl called CustomScrollbar. so I right-click on the solution, choose Add, select WPF and UserControl, give it a name, then click OK. Now I have CustomScrollbar.xaml and CustomScrollbar.xaml.vb in my project.. Here are the file contents so far:
<UserControl x:Class="RonM:CustomScrollbar" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" mc:Ignorable="d" d:DesignHeight="300" d:DesignWidth="300"><Grid></Grid></UserControl>
Namespace RonM Public Class CustomScrollbar End Class End Namespace
So the problem is, when I try to build the solution I get this error:
x:Class="RonM:CustomScrollbar" is not valid. 'RonM:CustomScrollbar' is not a valid class name. Line 1 Position 14.
If I remove the "RonM:" from the first line of the XAML file, it builds ok, but then I end up with 2 different user controls in my project, one with and one without namespace in the user control name in the toolbox. If I try to insert the one with the namespace into my MainWindow, it is empty. If I insert the one WITHOUT the namespace into my MainWindow, it seems to be ok.
So what am I doing wrong? The other 3 UserControls work just fine with a namespace declaration. It seems like I should be able to add a new one using the same syntax, right?
It's probably something very simple, but I can't see it.
Thanks...
