Submit button not Firing

Question

我有一個webform應用程序，它有一個提交按鈕來存儲到sql server。 這裏是它的代碼。

try 
     { 
      SqlConnection insc = new SqlConnection(@"Data Source=2011-GOA-RCC3\sqlexpress;Initial Catalog=S.I.-DBase-Web;Integrated Security=True"); 
      insc.Open(); 
      SqlCommand cmnd = new SqlCommand(); 
      cmnd.Connection = insc; 
      cmnd.CommandText = "Insert Into Global_DCR(Sr_No, Comp_ID, Br_Code, Br_Name, Region, Node, Comp_Date, Comp_Time, WAN_IP, Network_Type, Circuit_Type, Ciruit_ID, MLLN_ID, CBS_ATM_TBA, Link_Stat, Call_Cat, Problem_Des, Backup_Work, Status, Resolved_Date, Resolved_Time, Total_Downtime, BSNL_Details, Docket_ID, Action_Owner, Remark) Values(@Sr_No, @Comp_ID, @Br_Code, @Br_Name, @Region, @Node, @Comp_Date, @Comp_Time, @WAN_IP, @Network_Type, @Circuit_Type, @Ciruit_ID, @MLLN_ID, @CBS_ATM_TBA, @Link_Stat, @Call_Cat, @Problem_Des, @Backup_Work, @Status, @Resolved_Date, @Resolved_Time, @Total_Downtime, @BSNL_Details, @Docket_ID, @Action_Owner, @Remark)"; 
      cmnd.Parameters.AddWithValue("@Sr_No", Label2.Text); 
      cmnd.Parameters.AddWithValue("@Comp_ID", Label4.Text); 
      cmnd.Parameters.AddWithValue("@Comp_Date", TextBox1.Text); 
      cmnd.Parameters.AddWithValue("@Comp_Time", TextBox2.Text);

      cmnd.Parameters.AddWithValue("@Br_Name", TextBox4.Text);     
      cmnd.Parameters.AddWithValue("@Node", TextBox6.Text); 
      cmnd.Parameters.AddWithValue("@WAN_IP", TextBox7.Text); 
      cmnd.Parameters.AddWithValue("@Network_Type", DropDownList1.SelectedItem); 
      cmnd.Parameters.AddWithValue("@Circuit_Type", DropDownList2.SelectedItem); 
      cmnd.Parameters.AddWithValue("@Circuit_ID", TextBox10.Text); 
      cmnd.Parameters.AddWithValue("@MLLN_ID", TextBox11.Text); 
      cmnd.Parameters.AddWithValue("@CBS_ATM_TBA", TextBox12.Text); 
      cmnd.Parameters.AddWithValue("@Link_Stat", TextBox13.Text);

      cmnd.Parameters.AddWithValue("@Docket_ID", TextBox18.Text); 
      cmnd.Parameters.AddWithValue("@BSNL_Details", TextBox19.Text); 
      cmnd.Parameters.AddWithValue("@Action_Owner", TextBox20.Text); 
      cmnd.Parameters.AddWithValue("@Remarks", TextBox21.Text); 

      if (Request.Cookies["Region"] != null) 
      { 
       TextBox5.Text = Server.HtmlEncode(Request.Cookies["Region"].Value);//read cookie 

      } 

      //{ 
      // string a3 = "Not happening Bro1"; 
      // ClientScript.RegisterStartupScript(this.GetType(), "myalert", "alert('" + a3 + "');", true); 
      //} 
      // button execution breaks at this step. no error is thrown 

      //to set backup 
      if (RadioButtonList1.SelectedValue == "Yes") 
      { 
       string Yes = "Yes"; 
       cmnd.Parameters.AddWithValue("@Backup_Work", Yes); 
      } 
      if (RadioButtonList1.SelectedValue == "No") 
      { 
       string No = "No"; 
       cmnd.Parameters.AddWithValue("@Backup_Work", No); 
      } 
      //{ 
      // string a2 = "Not happening Bro2"; 
      // ClientScript.RegisterStartupScript(this.GetType(), "myalert", "alert('" + a2 + "');", true); 
      //} 

      //status 
      if (RadioButtonList2.SelectedValue == "Resolved") 
      { 
       string res = "Resolved"; 
       cmnd.Parameters.AddWithValue("@Status", res); 
       cmnd.Parameters.AddWithValue("@Resolved_Date", TextBox16.Text); 
       cmnd.Parameters.AddWithValue("@Resolved_Time", TextBox17.Text); 
       cmnd.Parameters.AddWithValue("@Total_Downtime", Label25.Text + ":" + Label26.Text + ":" + Label27.Text);//store three values in single table 

      } 
      if (RadioButtonList2.SelectedValue == "Pending") 
      { 
       string pen = "Pending"; 
       cmnd.Parameters.AddWithValue("@Status", pen); 
       cmnd.Parameters.AddWithValue("@Resolved_Date", pen); 
       cmnd.Parameters.AddWithValue("@Resolved_Time", pen); 
       cmnd.Parameters.AddWithValue("@Total_Downtime", pen); 
      } 
      //Session["Comp_ID"] = Label4.Text; 

      int mn = cmnd.ExecuteNonQuery(); 
      if (mn > 0) 
      { 
       string ab = "Incident With Incident ID"; 
       string abc = Convert.ToString(Label4.Text); 
       ClientScript.RegisterStartupScript(this.GetType(), "myalert", "alert('" + ab + abc + "');", true); 

      } 
      else 
      { 
       string sw = "Unable To Create Incident"; 
       ClientScript.RegisterStartupScript(this.GetType(), "myalert", "alert('" + sw + "');", true); 
      } 



     } 
     catch (Exception s) 
     { 
      ClientScript.RegisterStartupScript(this.GetType(), "myalert", "alert('" + s + "');", true); 
     } 
    } 

問題是代碼不工作。一旦我填寫頁面上的所有相關數據，並點擊提交按鈕，它不會保存到數據庫。 感謝您的幫助。

Answer 1

事實證明，有存儲下拉列表視圖項時存在問題。 新秀錯誤.....

Answer 2

問題：如果您的Region cookie是null您沒有插入任何默認值。

解決方案：您需要如果Region曲奇變得null添加的默認值。 你需要的其他塊添加到存儲默認值asbelow

試試這個：

if (Request.Cookies["Region"] != null) 
{ 
    TextBox5.Text = Server.HtmlEncode(Request.Cookies["Region"].Value);//read cookie 
} 
else{ 
    TextBox5.Text = String.Empty; 
} 

編輯：

試試這個：

if (RadioButtonList2.SelectedValue.ToString().Trim().Equals("Pending"))
