推荐答案

1。使用 OnCheckedChanged 事件（当Checked属性发生变化时要执行的函数的名称）单选按钮。



2.在所有单选按钮上为该事件调用相同的功能。



3.在这种情况下，检查单击了哪个单选按钮。



4.在标签上显示该单选按钮。



参考 - 如何在RadioButton中使用OnCheckedChanged事件 [ ^ ]，它提供了类似的要求。



因此，在您的aspx中，Radio Buttons将如下所示。

1. Use OnCheckedChanged event (the name of the function to be executed when the Checked property has changed) of Radio Button.

2. Call the same function on that event for all Radio Buttons.

3. In that event, check which radio button is clicked.

4. Show in label about that Radio Button.

Refer - How to use OnCheckedChanged event in RadioButton[^], which gives similar type of requirement.

So, in your aspx, Radio Buttons will look like below.

<asp:RadioButton

             ID="RadioButton1"

             runat="server"

             Text="RadioButton1"

             OnCheckedChanged="RadioButton_CheckedChanged"

             AutoPostBack="true">
</asp:RadioButton>
<asp:RadioButton

             ID="RadioButton2"

             runat="server"

             Text="RadioButton2"

             OnCheckedChanged="RadioButton_CheckedChanged"

             AutoPostBack="true">
</asp:RadioButton>
<asp:RadioButton

             ID="RadioButton3"

             runat="server"

             Text="RadioButton3"

             OnCheckedChanged="RadioButton_CheckedChanged"

             AutoPostBack="true">
</asp:RadioButton>
<asp:RadioButton

             ID="RadioButton4"

             runat="server"

             Text="RadioButton4"

             OnCheckedChanged="RadioButton_CheckedChanged"

             AutoPostBack="true">
</asp:RadioButton>

所以，你可以看到fu所有单选按钮的' OnCheckedChanged 事件调用RadioButton_CheckedChanged。



现在在cs页面中，如下所示。

So, as you can see the function "RadioButton_CheckedChanged" is called for all Radio Buttons'' OnCheckedChanged Event.

Now in cs page, do like below.

protected void RadioButton_CheckedChanged(object sender, System.EventArgs e)
{
      if (RadioButton1.Checked)
      {
            // Call function you want to call for "RadioButton1".
            Label1.Text = "You choose: " + RadioButton1.Text;
      }

      if (RadioButton2.Checked)
      {
            // Call function you want to call for "RadioButton2".
            Label1.Text = "You choose: " + RadioButton2.Text;
      }
      
      if (RadioButton3.Checked)
      {
            // Call function you want to call for "RadioButton3".
            Label1.Text = "You choose: " + RadioButton3.Text;
      }
      
      if (RadioButton4.Checked)
      {
            // Call function you want to call for "RadioButton4".
            Label1.Text = "You choose: " + RadioButton4.Text;
      }
}
