使用Silverlight的组合框绑定 [英] Combo box binding using silverlight

问题描述

大家好，所以我有两个组合框:

Hello guys, so I have two comboboxes:

<ComboBox Height="35" HorizontalAlignment="Left" Margin="343,67,0,0" Name="comboBox2" VerticalAlignment="Top" Width="273" SelectionChanged="comboBox2_SelectionChanged"    >
            <ComboBox.Items>

                <ComboBoxItem IsSelected="True" Content="Trial"  />
                <ComboBoxItem IsSelected="True" Content="Limited" />
                <ComboBoxItem IsSelected="True" Content="Pernament" />




                </ComboBox.Items>
        </ComboBox>

和

and

<ComboBox Height="35" HorizontalAlignment="Left" Margin="343,125,0,0" Name="comboBox1" VerticalAlignment="Top" Width="273" SelectionChanged="comboBox1_SelectionChanged">
            <ComboBoxItem Content="3 Months" IsSelected="True" />
            <ComboBoxItem Content="6 Months" />
            <ComboBoxItem Content="12 Months" />
            <ComboBoxItem IsSelected="True" Content="-" />
        </ComboBox>

我试图绑定它们，例如，如果第一个框的值不受限，则第二个组合框应被禁用，并且如果在文本框中选择了受限"，则必须显示此日期和月份.谢谢您提前提供帮助.

I am trying to bind them for example if value of first box isn''t Limited, second combo box should be disabled, and if Limited is selected in text box this date + months chosen must be displayed. Thanks for help in advance

推荐答案

在这种情况下，您只需要做一件事情，就必须使用IValueConverter:
在Silverlight中使用IValueConverter进行数据绑定 [

There is only onw thing to do in such a case, you will have to use an IValueConverter:
Data Binding Using IValueConverter in Silverlight[^]

You could bind the second combobox to isenabled and do the appropiate convertions from the selected values of the second one :)
