Question

鉴于，

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

在运行时，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，列可以编辑。

是否可以让添加记录功能正常工作，而“不”明确地将每个字段标记为可编辑？

感谢您的关注。

你最好的选择是在infragistics netadvantage论坛上问这个，但是说了......

据我所知，你想要的是一个只读数据网格（在其单元格上不可编辑），以便有一个可编辑的行来添加新项...

在CellValuePresenter下添加Style定位XamDatagrid.Resources。
这将检查给定的单元格值展示器是否已聚焦并表示添加新行。

如果是这样，它将通过某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>

所附行为如下......

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);
    }
}

希望这有帮助。
