Ingragistic XamGrid：新记录是不可编辑

Question

考虑，

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

在运行，我可以看到在网格之上的空新行。但新行中的列没有可编辑的！当我将每个字段标记为可编辑时，这些列是可编辑的。

是否有可能使添加记录功能工作，而“没有”明确标记每个字段为可编辑？

感谢您的关注。

您最好的选择是对的Infragistics NetAdvantage的论坛上问这个，不过话说回来......

据我所知，你想要的是一个只读数据网格（在其细胞不可编辑）有一个可编辑行添加新项...

1. 添加CellValuePresenter针对性StyleXamDatagrid.Resources下。
2. 这将检查给定的单元值演示者是否聚焦并表示添加新行。

3. 如果是这样，它会通过一些附加行为使父域可编辑。

   <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> 
   

而且附加的行为是如下...

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); 
    } 
} 

希望这有助于。
