在Silverlight 4 Datagrid上实现双击事件 [英] Implementing the double-click event on Silverlight 4 Datagrid

问题描述

任何好的灵魂都有一个例子来实现在Silverlight 4.0 DataGrid中双击事件由Prism引入的命令模式？

我尝试过以下操作：

 < data：DataGrid x：Name =dgUserRolesAutoGenerateColumns =FalseMargin =0Grid.Row = 0ItemsSource ={Binding Path = SelectedUser.UserRoles}IsReadOnly =False> 
< data：DataGrid.Columns> 
< data：DataGridTemplateColumn Header => 
< data：DataGridTemplateColumn.CellTemplate> 
< DataTemplate> 
< Button Width =20Height =20Click =Button_ClickCommand ={Binding EditRoleClickedCommand}CommandParameter ={Binding SelectedRole}/> 
< / DataTemplate> 
< / data：DataGridTemplateColumn.CellTemplate> 
< / data：DataGridTemplateColumn> 
< data：DataGridTextColumn Header =Role NameBinding ={Binding RoleName}/> 
< data：DataGridTextColumn Header =Role CodeBinding ={Binding UserroleCode}IsReadOnly =True/> 
< data：DataGridCheckBoxColumn Header =UDFM ManagedBinding ={Binding RoleIsManaged}IsReadOnly =True/> 
< data：DataGridCheckBoxColumn Header =UDFM Role AssignedBinding ={Binding UserroleIsUdfmRoleAssignment}IsReadOnly =True/> 
< data：DataGridTextColumn Header =Source UserBinding ={Binding SourceUser}IsReadOnly =True/> 
< / data：DataGrid.Columns> 
< / data：DataGrid> 
  

正如你所看到的，我尝试将命令挂在那里，而不是在我的查看模型

寻找一个很好的选择。

解决方案

，Button.Command不用于双击。它也可以与单击一起工作。

你需要这样改变。 ElementName = dgUserRoles，Path = DataContext。

  Command ={Binding ElementName = dgUserRoles，Path = DataContext.EditRoleClickedCommand}
  

Any good soul have an example of implementing the "Command Pattern" introduced by Prism on a double click event in a Silverlight 4.0 DataGrid?

I tried the following:

<data:DataGrid x:Name="dgUserRoles" AutoGenerateColumns="False" Margin="0" Grid.Row="0" ItemsSource="{Binding Path=SelectedUser.UserRoles}" IsReadOnly="False">
    <data:DataGrid.Columns>
        <data:DataGridTemplateColumn Header="">
            <data:DataGridTemplateColumn.CellTemplate>
                <DataTemplate>
                    <Button Width="20" Height="20" Click="Button_Click" Command="{Binding EditRoleClickedCommand}" CommandParameter="{Binding SelectedRole}" />
                </DataTemplate>
            </data:DataGridTemplateColumn.CellTemplate>
        </data:DataGridTemplateColumn>
        <data:DataGridTextColumn Header="Role Name" Binding="{Binding RoleName}" />
        <data:DataGridTextColumn Header="Role Code" Binding="{Binding UserroleCode}" IsReadOnly="True"/>
        <data:DataGridCheckBoxColumn Header="UDFM Managed" Binding="{Binding RoleIsManaged}" IsReadOnly="True" />
        <data:DataGridCheckBoxColumn Header="UDFM Role Assigned" Binding="{Binding UserroleIsUdfmRoleAssignment}" IsReadOnly="True" />
        <data:DataGridTextColumn Header="Source User" Binding="{Binding SourceUser}" IsReadOnly="True" />
    </data:DataGrid.Columns>
</data:DataGrid>

As you see I did try to hook up the Command there and it is not firing the event in my View Model.

Looking for a good alternative.

解决方案

First, Button.Command is not for double-click. It will work with single click as well.

You need to change like that. ElementName=dgUserRoles, Path=DataContext.

 Command="{Binding ElementName=dgUserRoles, Path=DataContext.EditRoleClickedCommand}"
