尽管 IsEnabled 设置为 true，DataGrid 中的按钮仍被禁用

Question

目标是将启用的

Button

插入到

DataGrid

的列中。

在以下 XAML 代码片段中，将

Button

插入到

DataGrid

中，并将

IsEnabled

属性设置为 true。

<DataGrid Name="DgData" HorizontalAlignment="Left" Height="306" Margin="10,119,0,0" VerticalAlignment="Top" Width="637" Background="White">
    <DataGrid.RowStyle>
        <Style TargetType="DataGridRow">
            <Setter Property="IsEnabled" Value="{Binding RelativeSource={RelativeSource Self},Path=IsNewItem,Mode=OneWay}" />
        </Style>
    </DataGrid.RowStyle>
    <DataGrid.Columns>
        <DataGridTextColumn Binding="{x:Null}" ClipboardContentBinding="{x:Null}" Header="Id" IsReadOnly="True" Visibility="Hidden"/>
        <DataGridTextColumn Header="Date" Binding="{Binding Date}" IsReadOnly="True" Width="100" CanUserResize="False"/>
        <DataGridTextColumn Header="Domain name" Binding="{Binding DomainName}" IsReadOnly="True" Width="105" CanUserResize="False"/>
        <DataGridTextColumn Header="Type" Binding="{Binding Relevance}" IsReadOnly="True" Width="65" CanUserResize="False"/>
        <DataGridTextColumn Header="Category" Binding="{Binding DomainName}" IsReadOnly="True" Width="65" CanUserResize="False"/>
        <DataGridTextColumn Header="Description" Binding="{Binding Content}" IsReadOnly="True" Width="200" CanUserResize="False"/>
        <DataGridTemplateColumn MinWidth="100" Header="Note" CanUserSort="True" CanUserResize="False">
            <DataGridTemplateColumn.CellTemplate>
                <DataTemplate>
                    <Button Name="BtnShowNotes" IsEnabled="True" Click="BtnShowNotes_OnClick">Show</Button>
                 </DataTemplate>
            </DataGridTemplateColumn.CellTemplate>
        </DataGridTemplateColumn>
    </DataGrid.Columns>
</DataGrid>

但是，执行应用程序时，该按钮被禁用。

是什么导致了这个问题？

Answer 1

您的

RowStyle

将整行的

IsEnabled

属性设置为

false

。删除此一项，

Button

应启用：

<DataGrid Name="DgData"  HorizontalAlignment="Left" Height="306" Margin="10,119,0,0" VerticalAlignment="Top" Width="637" Background="White">
    <DataGrid.Columns>
        <DataGridTextColumn Binding="{x:Null}" ClipboardContentBinding="{x:Null}" Header="Id" IsReadOnly="True" Visibility="Hidden"/>
        <DataGridTextColumn Header="Datum" Binding="{Binding Date}" IsReadOnly="True" Width="100" CanUserResize="False"/>
        <DataGridTextColumn Header="Doménové jméno" Binding="{Binding DomainName}" IsReadOnly="True" Width="105" CanUserResize="False"/>
        <DataGridTextColumn Header="Druh" Binding="{Binding Relevance}" IsReadOnly="True" Width="65" CanUserResize="False"/>
        <DataGridTextColumn Header="Kategorie" Binding="{Binding DomainName}" IsReadOnly="True" Width="65" CanUserResize="False"/>
        <DataGridTextColumn Header="Popis" Binding="{Binding Content}" IsReadOnly="True" Width="200" CanUserResize="False"/>
        <DataGridTemplateColumn MinWidth="100" Header="Poznámky" CanUserSort="True" CanUserResize="False">
            <DataGridTemplateColumn.CellTemplate>
                <DataTemplate>
                    <Button Name="BtnShowNotes" IsEnabled="True" Click="BtnShowNotes_OnClick">Zobrazit</Button>
                </DataTemplate>
            </DataGridTemplateColumn.CellTemplate>
        </DataGridTemplateColumn>
    </DataGrid.Columns>
</DataGrid>
