WPF工具包Datagrid的 - 你怎么把选择了吗？ [英] WPF Toolkit Datagrid - how do you turn selection off?

问题描述

我在WPF DataGrid中，我绑定到一个对象。

我在那里，我希望用户能够通过和蜱他们想要的一个DataGridCheckBoxColumn。问题是，他们必须为选择然后再次单击两次，一次检查/取消选中。如何在地球上你关闭此功能，我一直在寻找的方式长时间才找到这个问题的答案。数据网格具有的SelectionMode和SelectionUnit性能 - 两者都不接受'无'或'消失'

任何帮助表示赞赏！我的代码如下，以供参考。

 <我：DataGrid的保证金=15NAME =dgPreview
的AutoGenerateColumns =FALSECanUserSortColumns =真
 CanUserDeleteRows =真
背景=白
 ColumnHeaderHeight =20
 VerticalScrollBarVisibility =可见
 RowDetailsVisibilityMode =可见
> 
 
<我：DataGrid.Columns> 
<我：DataGridCheckBoxColumn了minWidth =50WIDTH =自动标题=包含绑定={结合包括}/> 
<我：DataGridTextColumn了minWidth =50WIDTH =自动标题=＃覆盖绑定={结合OverrideNumber}/> 
<我：DataGridTextColumn了minWidth =220WIDTH =*标题=名称绑定={绑定名称}/> 
<我：DataGridTextColumn了minWidth =50WIDTH =自动IsReadOnly =真头=预览绑定={结合预览}/> 
< /我：DataGrid.Columns> 
< /我：DataGrid的> 
  

解决方案

第一次单击放入编辑模式的单元，则在第二次点击允许你修改的复选框。您可以通过使用一个DataGridTemplateColumn而不是DataGridCheckBoxColumn更改此行为。这种替换您DataGridCheckBoxColumn：

 <我：DataGridTemplateColumn了minWidth =50WIDTH =自动标题=包含 SortMemberPath =包含> 
<我：DataGridTemplateColumn.CellTemplate> 
<&DataTemplate的GT; 
<复选框类型={StaticResource的DataGridCheckBoxStyle}=器isChecked{绑定路径=包含}/> 
< / DataTemplate中> 
< /我：DataGridTemplateColumn.CellTemplate> 
< /我：DataGridTemplateColumn> 
  

DataGridCheckBoxStyle只是使复选框看起来在DataGrid更好一点：

 <风格X：键=DataGridCheckBoxStyle的TargetType =复选框支持算法FMP ={StaticResource的{X：类型的CheckBox}}> 
< setter属性=VerticalAlignmentVALUE =中心/> 
< setter属性=保证金VALUE =8,0,3,0/> 
< /样式和GT; 
  

I have a datagrid in WPF that I am binding to an object.

I have a DataGridCheckBoxColumn on there which I want the users to be able to go through and tick the ones they want. Problem is they have to click twice, once for selection then again to check/uncheck. How on earth do you turn this off, I've been searching for way to long to find the answer to this. The datagrid has SelectionMode and SelectionUnit properties - neither of which accept 'none' or 'go away'

Any help is appreciated! My code is below for reference

<my:DataGrid Margin="15"  Name="dgPreview" 
                    AutoGenerateColumns="False" CanUserSortColumns="True" 
                         CanUserDeleteRows="True" 
                         Background="White" 
                         ColumnHeaderHeight="20" 
                         VerticalScrollBarVisibility="Visible" 
                         RowDetailsVisibilityMode="Visible" 
                         >

                <my:DataGrid.Columns>
                    <my:DataGridCheckBoxColumn  MinWidth="50" Width="Auto" Header="Include" Binding="{Binding Include}" />
                    <my:DataGridTextColumn MinWidth="50"  Width="Auto" Header="Override #" Binding="{Binding OverrideNumber}" />
                    <my:DataGridTextColumn MinWidth="220" Width="*" Header="Name" Binding="{Binding Name}" />
                    <my:DataGridTextColumn MinWidth="50" Width="Auto" IsReadOnly="True"  Header="Preview" Binding="{Binding Preview}" />
                </my:DataGrid.Columns>
            </my:DataGrid>

解决方案

The first click puts the cell in edit mode then the second click allows you to modify the checkbox. You can change this behavior by using a DataGridTemplateColumn instead of a DataGridCheckBoxColumn. Replace your DataGridCheckBoxColumn with this:

<my:DataGridTemplateColumn MinWidth="50" Width="Auto" Header="Include" SortMemberPath="Include">
   <my:DataGridTemplateColumn.CellTemplate>
      <DataTemplate>
         <CheckBox Style="{StaticResource DataGridCheckBoxStyle}" IsChecked="{Binding Path=Include}" />
      </DataTemplate>
   </my:DataGridTemplateColumn.CellTemplate>
</my:DataGridTemplateColumn>

DataGridCheckBoxStyle just makes the CheckBox look a little nicer in the DataGrid:

<Style x:Key="DataGridCheckBoxStyle" TargetType="CheckBox" BasedOn="{StaticResource {x:Type CheckBox}}">
   <Setter Property="VerticalAlignment" Value="Center" />
   <Setter Property="Margin" Value="8,0,3,0" />
</Style>
