にカスタムテキストボックスの名前を設定することはできません。WPFは、私はWPFのプログラムを作成していると私は、カスタムユーザーコントロールとカスタムテキストボックス</p> <p>私はVisual Studioで私の解決策を再構築するとき、私はこのエラーを取得を作成したユーザーコントロール
Cannot set Name attribute value 'SearchT' on element 'HintTextBox'. 'HintTextBox' is under the scope of element 'ClickableControl', which already had a name registered when it was defined in another scope
私は何が必要かわかりません。それとも私が間違っていた?誰かが私を助けることができる?以下のクラスはusercontrolとhinttextboxです。最後はxamlでどうやって実装したかです。
これは私が私のUserControl
TEXTBOX = HintTextBoxにテキストボックスを置く方法です:
名前空間View.custom_usercontrols { 公共部分クラスのHintTextBox:TextBoxの { のpublic static読み取り専用のDependencyProperty HintepDependencyProperty = DependencyProperty.Register( "ヒント"、typeof(文字列)、typeof(HintTextBox));
public string Hint
{
get
{
return (string)GetValue(HintepDependencyProperty);
}
set
{
SetValue(HintepDependencyProperty, value);
}
}
private string _text;
private bool _placeHolder;
public HintTextBox()
{
InitializeComponent();
if (Hint == null)
{
_text = "";
}
else
{
_text = Hint;
}
_placeHolder = true;
Text = _text;
Opacity = 0.2;
}
//extra code
}
}
これは私のUserControl = ClickableControl
namespace View.custom_usercontrols
{
[ContentProperty(nameof(Children))]
public partial class ClickableControl : UserControl
{
public static readonly DependencyPropertyKey ChildrenProperty = DependencyProperty.RegisterReadOnly(
nameof(Children), // Prior to C# 6.0, replace nameof(Children) with "Children"
typeof(UIElementCollection),
typeof(ClickableControl),
new PropertyMetadata());
public static readonly DependencyProperty HoverColorDependencyProperty = DependencyProperty.Register("HoverColor", typeof(Brush), typeof(HintTextBox));
public static readonly DependencyProperty SelectedColorDependencyProperty = DependencyProperty.Register("SelectedColor", typeof(Brush), typeof(HintTextBox));
public static readonly DependencyProperty SelectedDependencyProperty = DependencyProperty.Register("Selected", typeof(Boolean), typeof(HintTextBox));
public Brush HoverColor
{
get
{
return (Brush)GetValue(HoverColorDependencyProperty);
}
set
{
SetValue(HoverColorDependencyProperty, value);
}
}
public Brush SelectedColor
{
get
{
return (Brush)GetValue(SelectedColorDependencyProperty);
}
set
{
SetValue(SelectedColorDependencyProperty, value);
}
}
private Brush BackgroundColor { get; set; }
public Boolean Selected
{
get
{
return (Boolean)GetValue(SelectedDependencyProperty);
}
set
{
SetValue(SelectedDependencyProperty, value);
if (value)
{
Background = SelectedColor;
}
else
{
Background = BackgroundColor;
}
}
}
public UIElementCollection Children
{
get { return (UIElementCollection) GetValue(ChildrenProperty.DependencyProperty); }
private set { SetValue(ChildrenProperty, value); }
}
public ClickableControl()
{
InitializeComponent();
Children = Grid.Children;
}
//EXTRA CODE
}
}
