Anoop，

您可以将radiobuttonlist.selectedIndex = -1设置为清除选择.

谢谢，

RadioButtonList 具有方法ClearSelection.

 受保护的 无效 Save_Click(对象发​​件人，EventArgs e)
       {
           sexlist.ClearSelection();
       } 

这样可以解决您的问题.

Hi Anoop,

You can set radiobuttonlist.selectedIndex = -1 to clear selection.

Thanks,

RadioButtonList has a method ClearSelection.

protected void Save_Click(object sender, EventArgs e)
       {
           genderlist.ClearSelection();
       }

This will resolve your issue.
