c# – RadioButtonList：OnSelectedIndexChanged没有触发

我有一个aspx页面,我用OnSelectedindexChanged事件动态添加radiobuttonlist.如果我检查所选项目.我有2件物品.

对于第一个项目,事件触发良好,但是如果我选择其他选项,则事件不会触发：在代码下面..

事件只是解雇是我从“一些提供”改为“全部提供”另一种方式它不工作

添加RBL：

RadioButtonList dControl_b = new RadioButtonList();
                dControl_b.ID = "rbl_MinCriteria";
                dControl_b.RepeatDirection = System.Web.UI.WebControls.RepeatDirection.Horizontal;
                dControl_b.CssClass = "Font";
                dControl_b.Font.Name = "Arial";
                dControl_b.Font.Size = 8;
                dControl_b.ToolTip = "";
                dControl_b.Selectedindex = -1;
                dControl_b.SelectedindexChanged += new EventHandler(rbl_MinCriteria_SelectedindexChanged);
                dControl_b.AutopostBack = true;

检查所选项目：

if(rbl_MinCriteria.SelectedItem.ToString() == "All provided")
   {
       cbl_MinimumCriteria.Items[0].Selected = true;
       cbl_MinimumCriteria.Items[1].Selected = true;
       cbl_MinimumCriteria.Items[2].Selected = true;
       cbl_MinimumCriteria.Items[3].Selected = true;
       cbl_MinimumCriteria.Enabled = false;

       //*************************************************************
       if (ddl_CountryOccurence.SelectedValue != "Please choose")
       {
           ddl_CountryOccurence.Enabled = false;
       }
       else
       {
           ddl_CountryOccurence.Enabled = true;
       }

       //*************************************************************
       if (tb_DueDate.Text != "")
       {
           tb_DueDate.Enabled = false;
       }
       else
       {
           tb_DueDate.Enabled = true;
       }

       OtherControlI.Enabled = false;
       OtherControlII.Enabled = false;
       OtherControlIII.Enabled = false;
   }
   if (rbl_MinCriteria.SelectedItem.ToString() == "Some provided")
   {
       cbl_MinimumCriteria.Items[0].Selected = false;
       cbl_MinimumCriteria.Items[1].Selected = false;
       cbl_MinimumCriteria.Items[2].Selected = false;
       cbl_MinimumCriteria.Items[3].Selected = false;
       cbl_MinimumCriteria.Enabled = true;

       //*************************************************************
       if (ddl_CountryOccurence.SelectedValue != "Please choose")
       {
           ddl_CountryOccurence.Enabled = false;
       }
       else
       {
           ddl_CountryOccurence.Enabled = true;
       }

       //*************************************************************
       if (tb_DueDate.Text != "")
       {
           tb_DueDate.Enabled = false;
       }
       else
       {
           tb_DueDate.Enabled = true;
       }

       OtherControlI.Enabled = false;
       OtherControlI.Selectedindex = -1;
       OtherControlII.Enabled = false;
       OtherControlII.Selectedindex = -1;
       OtherControlIII.Enabled = false;
       OtherControlIII.Selectedindex = -1;
   }

任何帮助和评论非常感谢

在RadioButtonList上,将AutopostBack属性设置为true.
