Question

我的Windows Phone 7应用程序中有一个表单，其中包含一些文本框和一个单选按钮。我想在单击重置按钮时重置文本框和单选按钮的值。我能够清除文本框但不知道如何清除单选按钮的值。请帮忙：

我的表格是：

<TextBox GotFocus="OnGotFocus" Canvas.Left="6" Canvas.Top="6" Height="74" Name="name" Text="*Name" Width="453" BorderThickness="0"/>
            <TextBox GotFocus="OnGotFocus1" Canvas.Left="6" Canvas.Top="66" Height="74" Name="age" Text="*Age" Width="453" BorderThickness="0" />
            <TextBlock Canvas.Left="20" Canvas.Top="157" Height="44" Name="gen" Text="Gender" Foreground="Black" FontFamily="Verdana" FontSize="24" Width="134" />
            <RadioButton Canvas.Left="139" Canvas.Top="157" FontStyle="Italic" Foreground="Black" Content="Male" Height="71" Name="male" Width="154" />
            <RadioButton Canvas.Left="139" Canvas.Top="207"  FontStyle="Italic" Foreground="Black" Content="Female" Height="71" Name="fem" Width="140" />
            <TextBox GotFocus="OnGotFocus2" Canvas.Left="6" Canvas.Top="267" Height="74" Name="sadd" Text="*Street Address" Width="453" BorderThickness="0"/>
            <TextBox GotFocus="OnGotFocus3" Canvas.Left="6" Canvas.Top="327" Height="74" Name="cadd" Text="*City Address" Width="453" BorderThickness="0"/>
            <TextBox GotFocus="OnGotFocus4" Canvas.Left="6" Canvas.Top="387" Height="74" Name="eadd" Text="*Email Address" Width="453" BorderThickness="0"/>
            <TextBox GotFocus="OnGotFocus5" Canvas.Left="6" Canvas.Top="447" Height="74" Name="phn" Text="*Phone" Width="453" BorderThickness="0"/>
            <TextBox GotFocus="OnGotFocus6" Canvas.Left="6" Canvas.Top="507" Height="74" Name="zip" Text="*Zip Code" Width="453" BorderThickness="0"/>

点击重置按钮时重置的代码是：

private void reset_Click(object sender, RoutedEventArgs e)
    {
        name.Text = "";
        age.Text  = "";
        sadd.Text = "";
        cadd.Text = "";
        eadd.Text = "";
        phn.Text  = "";
        zip.Text  = "";
    }

请添加我应添加的代码以重置单选按钮

现在点击提交按钮，如果我想检查是否已选择男性或女性，我该怎么做。对于文本框，我正在执行以下代码：

   private void submit_Click(object sender, RoutedEventArgs e)
    {
        if (name.Text == "")
        {
            MessageBox.Show("Please Enter the name");
            name.Focus();
        }


    }

Answer 1

有一个名为content的属性，它等同于文本框文本属性

这就是你要设置它的方式

male.IsChecked=false;
male.Content=String.Empty;

关于编辑。

为两个radiobuttons分配一个公共groupname属性。即

<RadioButton Canvas.Left="139" Canvas.Top="157" FontStyle="Italic" GroupName="Gender" Foreground="Black" Content="Male" Height="71" Name="male" Width="154" />
<RadioButton Canvas.Left="139" Canvas.Top="207"  FontStyle="Italic" GroupName="Gender" Foreground="Black" Content="Female" Height="71" Name="fem" Width="140" />

这使得每次在xaml中选择两个中的任何一个。

现在在代码中获取radiobutton的值应该是。

if(male.IsChecked==true)
{
string gender=male.Content.ToString();
}
else if(female.isChecked==true)
{
string gender=female.Content.ToString();
}
else    //none of them is selected.
{
 MessageBox.Show("Text");
}
