WPF UserControl Warning
-
Hi, What can cause the following warning occurs?
The element 'StackPanel' in namespace 'http://schemas.microsoft.com/winfx/2006/xaml/presentation' has invalid child element 'FileInputBox' in namespace 'clr-namespace:UserControlTest'. List of possible elements expected: 'StackPanel.CanHorizontallyScroll, StackPanel.CanVerticallyScroll, StackPanel.ScrollOwner, StackPanel.Background, StackPanel.IsItemsHost, StackPanel.Style, StackPanel.OverridesDefaultStyle, StackPanel.Triggers, StackPanel.Resources, StackPanel.DataContext, StackPanel.Language, StackPanel.Tag, StackPanel.InputScope, StackPanel.LayoutTransform, StackPanel.Width, StackPanel.MinWidth, StackPanel.MaxWidth, StackPanel.Height, StackPanel.MinHeight, StackPanel.MaxHeight, StackPanel.Margin, StackPanel.FocusVisualStyle, StackPanel.Cursor, StackPanel.ForceCursor, StackPanel.ToolTip, StackPanel.ContextMenu, StackPanel.InputBindings, StackPanel.CommandBindings, StackPanel.AllowDrop, StackPanel.RenderSize, StackPanel.RenderTransform, StackPanel.RenderTransformOrigin, StackPanel.Opacity, StackPanel.OpacityMask, StackPanel.BitmapEffect, StackPanel.BitmapEffectInput, StackPanel.ClipToBounds, StackPanel.Clip, StackPanel.SnapsToDevicePixels, StackPanel.IsEnabled, StackPanel.IsHitTestVisible, StackPanel.Focusable, sgUIElement...It's happen when I add my own UserControl, of course the application is working in proper way. thanks in advance
