推荐答案

您正在代码中的某处设置单选按钮，如果验证失败，可能无法执行。

尝试在其中一个单选按钮中添加Checked =True，以便默认选中它。

You're setting radio buttons somewhere in code which probably doesn't execute if validation fails.
Try adding Checked="True" in one of radio buttons so that it is checked by default.

在您的UI代码中，此处未指定Checked =true RadioButton Control。



如果你在.cs Page_Load事件上指定它，你必须像这样写。

In your UI code, Here you not specify Checked="true" of RadioButton Control.

And if you specify it on .cs Page_Load Event than you have to write it like this.

protected void Page_Load(object sender, EventArgs e)
{
        if (!IsPostBack)
        {
            prRdBtn.Checked = true;
        }
}
