Question

Given,

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

接下来,我可以看到一个网顶上的空洞的新行。但是,新行一栏中没有任何一栏是不容置疑的! 当我把每个领域标明为不容争辩时,各栏是可调的。

在“不”明确标明每个领域为不容置疑的标记时,是否能够增加记录功能?

Thanks for your interest.

最好要问一下的是,在不友善的“净优势”论坛上,但说......

我理解,你想要的是只读数据网(囚室不能校正),以便有一条可观的行文添加新的项目......

Add a CellValuePresenter targetted Style under XamDatagrid.Resources.
This will check if the given cell value presenter is focused and represents the add new row.

如果是的话,它将通过某些附带的行为使母子的田地变得不可调和。

<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);
    }
}

希望这一帮助。
