wpf - Ingragistic XamGrid：新记录不可编辑

Question

鉴于，

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

运行时，我可以在网格顶部看到一个空的新行。但是新行中的所有列都不可编辑！当我将每个字段标记为可编辑时，这些列是可编辑的。

是否可以在“不”明确地将每个字段标记为可编辑的情况下使添加记录功能正常工作？

感谢您的关注。

你最好在 infragistics netadvantage 论坛上问这个问题，但话虽如此......

据我了解，您想要的是一个只读数据网格（在其单元格上不可编辑）具有可编辑的行来添加新项目......

1. 在CellValuePresenter. Style_ XamDatagrid.Resources_
2. 这将检查给定的单元格值呈现器是否聚焦并表示添加新行。

3. 如果是这样，它将通过一些附加行为使父字段可编辑。

   <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>
   

附加的行为如下......

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);
    }
}

希望这可以帮助。
