wpf自定义绑定数据

 自定义绑定数据，通过Binding Path进行绑定

1、ItemsSource="{Binding SelFloorData}"（在datagrid中绑定数据）

2、Binding="{Binding FloorName}（绑定具体的数据成员）

3、解决checkbox中需要点击两次才能选中，重写DataGridTemplateColumn

4、列头和内容居中

<DataGrid x:Name="dataGrid" HorizontalAlignment="Center" VerticalAlignment="Top" Height="330" Width="170" Margin="8,0,0,0" 
                  RowHeaderWidth="0" HorizontalContentAlignment="Center" IsSynchronizedWithCurrentItem="True" 
                  ItemsSource="{Binding SelFloorData}" CanUserAddRows="False" AutoGenerateColumns="False"
                  >
            
            <!--为了解决CheckBox选中两次才可改变状态-->
            <DataGrid.Columns>
                <!--相关属性不能放到CheckBox那一行，否则影响居中等-->
                <DataGridTemplateColumn Header="选择" CanUserResize="False" Width="40" >
                    <!--列头居中-->
                    <DataGridTemplateColumn.HeaderStyle>
                        <Style TargetType="DataGridColumnHeader">
                            <Setter Property="HorizontalContentAlignment" Value="Center"></Setter>
                        </Style>
                    </DataGridTemplateColumn.HeaderStyle>
                    <!--内容居中-->
                    <DataGridTemplateColumn.CellTemplate>
                        <DataTemplate>
                            <!--绑定数据-->
                            <CheckBox Name="SelCheckBox" HorizontalAlignment="Center" IsChecked="{Binding SelCurFloor}"/>
                        </DataTemplate>
                    </DataGridTemplateColumn.CellTemplate>
                </DataGridTemplateColumn>

                <DataGridTemplateColumn Header="楼层" Width="60">
                    <!--列头居中-->

                    </DataGridTemplateColumn.HeaderStyle>
                    <!--内容居中-->
