Question

我正在使用silverlight4 mvvmlight。我想从Datagrid中触发命令事件。我的DataGrid代码是：

  <sdk:DataGrid ItemsSource="{Binding ScheduleInProcessSource.View, Mode= TwoWay}" SelectedItem="{Binding CurrentActivity, Mode=TwoWay}" AutoGenerateColumns="False">
            <sdk:DataGrid.Columns>
                <sdk:DataGridTextColumn Header="Start" Binding="{Binding Path=Start}"/>

                <sdk:DataGridTextColumn Header="Subject" Binding="{Binding Path=Subject}"/>

                <sdk:DataGridTextColumn Header="StoreName" Binding="{Binding Path=Outlet.OutletName}"/>
                <sdk:DataGridTextColumn Header="AddressLine1" Binding="{Binding Path=Outlet.Address.AddressLine1}"/>
                <sdk:DataGridTextColumn Header="AddressLine2" Binding="{Binding Path=Outlet.Address.AddressLine2}"/>
                <sdk:DataGridTextColumn Header="OwnerName" Binding="{Binding Path=Outlet.OwnerName}"/>
                <sdk:DataGridTextColumn Header="ContactName" Binding="{Binding Path=Contact.FirstName}"/>
                <sdk:DataGridTextColumn Header="PhoneNo" Binding="{Binding Path=Outlet.Phone}"/>
                <sdk:DataGridTextColumn Header="MobileNo" Binding="{Binding Path=Outlet.Mobile}"/>

                <sdk:DataGridTemplateColumn IsReadOnly="False">
                    <sdk:DataGridTemplateColumn.CellTemplate>
                        <DataTemplate>
                            <HyperlinkButton Content="Edit" Click="btnEdit_Click"/>
                        </DataTemplate>
                    </sdk:DataGridTemplateColumn.CellTemplate>
                </sdk:DataGridTemplateColumn>
                <sdk:DataGridTemplateColumn IsReadOnly="False">
                    <sdk:DataGridTemplateColumn.CellTemplate>
                        <DataTemplate>
                            <HyperlinkButton Content="Resume" Command="{Binding ResumeAuditing}"/>
                        </DataTemplate>
                    </sdk:DataGridTemplateColumn.CellTemplate>
                </sdk:DataGridTemplateColumn>
                <sdk:DataGridTemplateColumn IsReadOnly="False">
                    <sdk:DataGridTemplateColumn.CellTemplate>
                        <DataTemplate>
                            <HyperlinkButton Content="Delete" Command="{Binding DeleteCommand}"/>
                        </DataTemplate>
                    </sdk:DataGridTemplateColumn.CellTemplate>
                </sdk:DataGridTemplateColumn>
            </sdk:DataGrid.Columns>
        </sdk:DataGrid>

但命令不起作用。我怎么能克服这种情况？请帮帮我..

我找到了解决方案

  <sdk:DataGrid ItemsSource="{Binding ScheduleInProcessSource.View, Mode= TwoWay}" SelectedItem="{Binding CurrentActivity, Mode=TwoWay}" AutoGenerateColumns="False" x:Name="dgInProcess">
            <sdk:DataGrid.Columns>
                <sdk:DataGridTextColumn Header="Start" Binding="{Binding Path=Start}"/>

                <sdk:DataGridTextColumn Header="Subject" Binding="{Binding Path=Subject}"/>

                <sdk:DataGridTextColumn Header="StoreName" Binding="{Binding Path=Outlet.OutletName}"/>
                <sdk:DataGridTextColumn Header="AddressLine1" Binding="{Binding Path=Outlet.Address.AddressLine1}"/>
                <sdk:DataGridTextColumn Header="AddressLine2" Binding="{Binding Path=Outlet.Address.AddressLine2}"/>
                <sdk:DataGridTextColumn Header="OwnerName" Binding="{Binding Path=Outlet.OwnerName}"/>

                <sdk:DataGridTextColumn Header="MobileNo" Binding="{Binding Path=Outlet.Mobile}"/>

                <sdk:DataGridTemplateColumn IsReadOnly="False">
                    <sdk:DataGridTemplateColumn.CellTemplate>
                        <DataTemplate>
                            <HyperlinkButton Content="Edit" Click="btnEdit_Click"/>
                        </DataTemplate>
                    </sdk:DataGridTemplateColumn.CellTemplate>
                </sdk:DataGridTemplateColumn>
                <sdk:DataGridTemplateColumn IsReadOnly="False">
                    <sdk:DataGridTemplateColumn.CellTemplate>
                        <DataTemplate>
                            <HyperlinkButton Content="Resume">
                                <i:Interaction.Triggers>
                                    <i:EventTrigger EventName="Click">
                                        <cmd:EventToCommand Command="{Binding Source={StaticResource VMLocator}, Path=ScheduleViewModel.ResumeAuditing}" PassEventArgsToCommand="True"/>
                                    </i:EventTrigger>
                                </i:Interaction.Triggers>
                            </HyperlinkButton>
                        </DataTemplate>
                    </sdk:DataGridTemplateColumn.CellTemplate>
                </sdk:DataGridTemplateColumn>
                <sdk:DataGridTemplateColumn IsReadOnly="False">
                    <sdk:DataGridTemplateColumn.CellTemplate>
                        <DataTemplate>
                            <HyperlinkButton Content="Delete">
                                <i:Interaction.Triggers>
                                    <i:EventTrigger EventName="Click">
                                        <cmd:EventToCommand Command="{Binding Source={StaticResource VMLocator}, Path=ScheduleViewModel.DeleteCommand}" PassEventArgsToCommand="True"/>
                                    </i:EventTrigger>
                                </i:Interaction.Triggers>


                            </HyperlinkButton>
                        </DataTemplate>
                    </sdk:DataGridTemplateColumn.CellTemplate>
                </sdk:DataGridTemplateColumn>
            </sdk:DataGrid.Columns>
        </sdk:DataGrid>

这将有效..
