帶有文本框的二維動態列表視圖

Question

這是一個動態列表視圖，帶有動態標題和行。但這裏的問題是，文我嘗試使用文本框作爲

xaml = "<DataTemplate><TextBox VerticalAlignment=\"Center\" TextChanged=\"{Binding " + propName + "}\" > " + propName + "</TextBox></DataTemplate>"; 

，而不是一個複選框，在CreateDataTemplate點擊幹訓局後值不能extratcted方法的結合。

這裏是CheckBox的代碼。那麼任何人都可以幫我解決問題。我也需要在文本框內的值。謝謝你在前進

Answer 1

使用這樣

xaml = "<DataTemplate><TextBox VerticalAlignment=\"Center\" Tag=\"{Binding " + propName + ", Mode=TwoWay}\" > " + propName + "</TextBox></DataTemplate>"; 

文本框的數據模板添加樣式文本框來你的listview.resources

  <Style TargetType="{x:Type TextBox}"> 
       <EventSetter Event="TextChanged" Handler="TextBox_TextChanged"></EventSetter> 
      </Style> 

的處理程序添加到您的代碼隱藏

private void TextBox_TextChanged(object sender, TextChangedEventArgs e) 
    { 
     (sender as TextBox).Tag = true; 
    } 

這會像你的複選框例子。
