我有多個(gè)單選按鈕，我使用 GroupName 來(lái)選擇至少 2 個(gè)選項(xiàng)中的 1 個(gè)。我似乎無(wú)法獲得 GroupName，因此我可以驗(yàn)證以確保已通過(guò)提交按鈕選擇了 2 個(gè)中的 1 個(gè)。 <myRepeater> <asp:CustomValidator ID="CustomValidator1" runat="server" ErrorMessage="* Select an option" ForeColor="#ff0000" OnServerValidate="option1_Validation" Display="Dynamic" /> <asp:RadioButton ID="rdOption1" Text="Option_1" GroupName="gnOption1" runat="server" /> <asp:RadioButton ID="rdOption2" Text="Option_2" GroupName="gnOption1" runat="server" /> </myRepeater>代碼： protected void option1_Validation(object source, ServerValidateEventArgs args) { bool itemSelected = false; foreach (RepeaterItem ri in myRepeater.Items) { RadioButton rb= (RadioButton)ri.FindControl("gnOption1"); { if (rb.GroupName == "gnOption1" && rb.Checked == true) { itemSelected = true; } args.IsValid = itemSelected; } } }

您必須將發(fā)件人對(duì)象轉(zhuǎn)換為自定義驗(yàn)證器：
CustomValidator myCustomValidator = (CustomValidator)sender;
然后找到 CustomValidator 的父項(xiàng)，在本例中為 Repeater Item：
RepeaterItem ri = (RepeaterItem)myCustomValidator.Parent;
最后獲得控制權(quán)：
RadioButton rb= (RadioButton)ri.FindControl("gnOption1");
您必須根據(jù)自己的需要進(jìn)行調(diào)整。

protected void game1_Validation(object sender, ServerValidateEventArgs args)
{
CustomValidator CustomValidator1 = (CustomValidator)sender;
bool itemSelected = false;
RepeaterItem ri = (RepeaterItem)CustomValidator1.Parent;
{
if (ri is RadioButton)
{
RadioButton rb = (RadioButton)ri.FindControl("gnOption11");
if (rb.GroupName == "gnOption1" && rb.Checked == true)
{
itemSelected = true;
}
}
}
args.IsValid = itemSelected;
}
