Ingragistic XamGrid：新記錄是不可編輯

Question

考慮，

<igDP:XamDataGrid Name="dataGrid" 
          DataSource="{Binding RecordList}"> 
      <igDP:XamDataGrid.FieldLayoutSettings > 
       <igDP:FieldLayoutSettings AllowAddNew="true" AddNewRecordLocation="OnTopFixed"/> 
      </igDP:XamDataGrid.FieldLayoutSettings> 

在運行，我可以看到在網格之上的空新行。但新行中的列沒有可編輯的！當我將每個字段標記爲可編輯時，這些列是可編輯的。

是否有可能使添加記錄功能工作，而「沒有」明確標記每個字段爲可編輯？

感謝您的關注。

您最好的選擇是對的Infragistics NetAdvantage的論壇上問這個，不過話說回來......

據我所知，你想要的是一個只讀數據網格（在其細胞不可編輯）有一個可編輯行添加新項...

1. 添加CellValuePresenter針對性StyleXamDatagrid.Resources下。
2. 這將檢查給定的單元值演示者是否聚焦並表示添加新行。

3. 如果是這樣，它會通過一些附加行爲使父域可編輯。

   <igDP:XamDataGrid Grid.Row="1" 
           DataSource="{Binding}" 
           AutoFit="True"> 
       <igDP:XamDataGrid.Resources> 
        <Style TargetType="{x:Type igDP:CellValuePresenter}"> 
         <Style.Triggers> 
          <MultiDataTrigger>       
           <MultiDataTrigger.Conditions> 
            <Condition Binding="{Binding IsFocused, 
               RelativeSource={RelativeSource Self}}" 
               Value="True"/> 
            <Condition Binding="{Binding Record.IsAddRecord, 
               RelativeSource={RelativeSource Self}}" 
               Value="True"/> 
           </MultiDataTrigger.Conditions> 
           <Setter 
            Property="local:CellValuePresenterBehavior.AllowFieldEdit" 
            Value="True"/> 
          </MultiDataTrigger> 
         </Style.Triggers> 
        </Style> 
       </igDP:XamDataGrid.Resources> 
       <igDP:XamDataGrid.FieldLayouts> 
        <igDP:FieldLayout> 
         <!-- Only show the first 4 fields to keep the display simple --> 
         <igDP:Field Name="Key" Visibility="Visible">       
          <igDP:Field.Settings> 
           <igDP:FieldSettings 
             EditAsType="{x:Type System:String}" 
            EditorType="{x:Type Editors:XamTextEditor}" 
             AllowEdit="False"/> 
          </igDP:Field.Settings> 
         </igDP:Field> 
         <igDP:Field Name="Value" Visibility="Visible"> 
          <igDP:Field.Settings> 
           <igDP:FieldSettings 
             EditAsType="{x:Type System:String}" 
            EditorType="{x:Type Editors:XamTextEditor}" 
             AllowEdit="False"/> 
          </igDP:Field.Settings> 
         </igDP:Field> 
        </igDP:FieldLayout> 
       </igDP:XamDataGrid.FieldLayouts> 
       <igDP:XamDataGrid.FieldLayoutSettings> 
        <igDP:FieldLayoutSettings AutoGenerateFields="False" 
               AllowAddNew="True" 
               AddNewRecordLocation="OnTopFixed" 
               HighlightAlternateRecords="True"/> 
       </igDP:XamDataGrid.FieldLayoutSettings> 
   </igDP:XamDataGrid> 
   

而且附加的行爲是如下...

public class CellValuePresenterBehavior 
{ 
    public static DependencyProperty AllowFieldEditProperty 
     = DependencyProperty.RegisterAttached(
      "AllowFieldEdit", 
      typeof(bool), 
      typeof(CellValuePresenterBehavior), 
      new PropertyMetadata(false, OnAllowFieldEditChanged)); 

    private static void OnAllowFieldEditChanged(
     DependencyObject depObj, 
     DependencyPropertyChangedEventArgs args) 
    { 
     var cvp = depObj as CellValuePresenter; 
     if (cvp != null) 
     { 
      cvp.Field.Settings.AllowEdit = (bool)args.NewValue; 
     } 
    } 

    public static bool GetAllowFieldEdit(DependencyObject depObj) 
    { 
     return (bool) depObj.GetValue(AllowFieldEditProperty); 
    } 

    public static void SetAllowFieldEdit(DependencyObject depObj, bool value) 
    { 
     depObj.SetValue(AllowFieldEditProperty, value); 
    } 
} 

希望這有助於。
