我有两个中继器控件，一个在另一个内部，在内部中继器中有一个占位符，其中动态生成单选按钮。我想找到单选按钮控件来检查它是否被选中？我希望首先在代码中定义的按钮提交/单击事件中执行所有功能？
if (!Page.IsPostBack)

// Just for testing : replace with query to DB

//SubName = ds.Tables[0].Rows[i].ItemArray[3].ToString();
DataSet oDs = SqlHelper.ExecuteDataset(sCon, "Ps_Quiz_OnlineTest_QuestionsWithOptions_Get", QuesID);
SomeDatatable.Merge(oDs.Tables[0]);
}
removeDuplicatesRows(SomeDatatable);
