Question

我想采用Datagrid Cell的事件触发器。我的意思是说我想写这样的东西

**<EventTrigger EventName="MouseEnter">**

然后从XAML调用函数：

void Cell_MouseEnter（object sender，MouseEventArgs e）

我该怎么做：

我在XAML中有这个

    <ctrls:RhinoDataGrid x:Name="dataGrid" Grid.Row="1" Margin="5" ItemsSource="{Binding Model.CurrentDataTable}"   
                             Style="{StaticResource RhinoDataGridBaseStyle}" IsReadOnly="{Binding Model.IsLinkFile}"
                             SelectedValue="{Binding Model.CurrentDataRow}" SelectedValuePath="Row"                                 SetAutomappingOnOff="{Binding IsAutoMap, Mode=TwoWay}" >
            </ctrls:RhinoDataGrid>


     <Style TargetType="{x:Type DataGridCell}">
            <Setter Property="BorderBrush" Value="Transparent"></Setter>
            <Setter Property="BorderThickness" Value="2"></Setter>
            <Style.Triggers>
                <Trigger Property="IsSelected" Value="True">
                    <Setter Property="Foreground" Value="White"></Setter>
                    <Setter Property="BorderBrush" Value="{DynamicResource ActiveItemBrush}"></Setter>
                    <Setter Property="BorderThickness" Value="2"></Setter>
                </Trigger>
            </Style.Triggers>

请帮忙

Answer 1

请检查“ IsMouseOver ”。我假设“ RhinoDataGrid ”继承自我们已知的WPF的DataGrid。

Answer 2

<Style TargetType="{x:Type DataGridCell}">
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="{x:Type DataGridCell}">
              <Grid Mouse.MouseEnter="Cell_MouseEnter" Background="{TemplateBinding Background}">       
                 <ContentPresenter/>
              </Grid>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>

您将EventSetter与EventTrigger ....

混淆

  <Style TargetType="{x:Type DataGridCell}"> 
       <EventSetter Event="MouseEnter" Handler="Cell_MouseEnter"/>
  </Style>
