  You should use the int.TryParse to convert to an integer. If the value in the textbox is not able to be converted to an integer you will not get an error

  Hi Abdul,

  What's the content do you input in the PatID_NO TextBox?

  Using int.TryParse to avoid error

  int PatID= 0;
  int.TryParse(PatID_NO.Text, out PatID);
  if (PatID> 0 )//text box value is integer
  {
  //parse success, PatID is change value
  }

  PatID_NO.Text will calculate ID from SIDC class..,, with out inserting any value its throwing catch ERROR 20 
  
   protected void Button1_Click(object sender, EventArgs e)
  {
  if (PatID_NO.Text != "")
  {
  SIDC a = new SIDC();
  int n;
  n = a.valid_re_int(PatID_NO.Text);
  if (n > 3)
  {
  Message("Error as well as make sure identification number"", this); return; } else PatID_NO.Focus(); }  
   else   
  PatID_NO.Focus(); 
  try { if (NameTxtBx.Text == "" || ToTxtBx0.Text == "" || DropDownList1.SelectedIndex == 0 || RadioButtonList2.SelectedIndex == -1 || ( PatID_NO.Text == null)|| (Convert.ToUInt64(PatNo.Text) <= 0) || (Convert.ToUInt64(PatNo.Text) > 200000000))
   {
   Message("Error: Please make sure that all fields are entered correctly", this);
   return;
   } 
  else
   { 
  try
   { 
  string Patient_name = NameTxtBx.Text, Export_TO = ToTxtBx0.Text, repType = RadioButtonList2.SelectedValue ;  
   int PatNoVal; PatNoVal = Convert.ToInt32(PatNo.Text); 
  PatNoVal = int.Parse(PatNo.Text);
  

   PatID = Convert.ToInt32(PatID_NO.Text); 
  PatID = int.Parse(PatID_NO.Text); 
  DateTime today = Convert.ToDateTime(DateTime.Now.ToShortDateString()); 
  System.Nullable<decimal> idcount = null; 
  int? replay_To_type = Int16.Parse(DropDownList1.SelectedValue); 
  try   {   TransDataContext db = new TransDataContext();   
  try {   
  var q = db.Transaction(Patient_name, Export_TO,replay_To_type,null,repType,PatNoVal,PatID,ref idcount);
  

  } 
  catch 
  { 
  Message("block 3:There is an error in the entry form required, please contact the Department of Computer", this);   
  }  
   } catch { Message("block 2: ERROR CONTACT YOUR SYSTEM ADMINISTRATOR", this);
   }  
   PatNo.Text = ""; 
  NameTxtBx.Text = "";
   ToTxtBx0.Text = ""; 
  DropDownList1.SelectedIndex = -1; 
  RadioButtonList2.SelectedIndex = -1;   
  }
   catch { Message(" ERROR 20", this); 
  }  
   } } 
  catch
   { 
  Message("Error: Make sure you enter the data correctly  ", this); 
  } 
  }

   int PatID;                                                  
                          PatID = Convert.ToInt32(PatID_NO.Text); 

  
  

  These  2 lines are enough to convert the string to int.

  Verify the datatype in ur database table whether it is int or not.

  and check it is Identity column or not? If it is identity u can't assign value for that.

  And post the error msg here .....

  Be what u want to be...Do wat u want to do...
  
  Mark as answer,if it helped U!

  Hi Abdul,

  Use the following.

  int PatNoVal;
  PatNoVal = Convert.ToInt32(((PatNo.Text != null) ? ((PatNo.Text.ToString().Trim().Length > 0) ? PatNo.Text.ToString().Trim() : "0") : "0"));
