WPF 控件之ComboBox绑定[2]

最近感觉新的方法Binding comboBox用起来很好用。

记录一下:

<ComboBox Grid.Row="0" Grid.Column="1" VerticalAlignment="Center" HorizontalAlignment="Left" MinWidth="120"
                              x:Name="cboFamilyName" 
                              DisplayMemberPath="DisplayName"  
                              SelectedValuePath="idRow" 
                              IsEditable="True" 
                              IsReadOnly="True"
                              ItemsSource="{Binding MyList}"
                              SelectedValue="{Binding Path=SelectedID, Mode=TwoWay}"
                              />

MyList就是某一个Model的list, Model中有idRow和DisplayName

SelectedID表示选中的idRow,放到这个变量中。

选中后,有时候会出现一个讨厌的红色矩形框。去掉矩形框方法(http://stackoverflow.com/questions/4135955/remove-red-rectangle-around-combobox):

Validation.ErrorTemplate="{x:Null}"


About modify the Validation.ErrorTemplate
<ControlTemplate x:Key="ComboBoxValidationErrorTamplate">
                <DockPanel>
                    <Border BorderBrush="Blue" BorderThickness="4">
                        <AdornedElementPlaceholder />
                    </Border>
                </DockPanel>
            </ControlTemplate>
And then use it in your ComboBox like
<ComboBoxValidation.ErrorTemplate="{StaticResource ComboBoxValidationErrorTamplate}"
          ...>
