Where is your Update query?!!

helloworld2020 8-Nov-12 4:53am

And why you're insisting using just one button for Save and Update? It will be better if you put two buttons. Otherwise it would be confusing

try something like this:

C#

  using (SqlCommand cmd =
 new SqlCommand("SELECT Profile_ID FROM YourTable", cn))

 SqlDataReader reader = cmd.ExecuteReader();

 if (reader.HasRows)
 {
     while (reader.Read())
     {
         String textReaded = reader["Profile_ID"].ToString();

     }
 }

if (txtReaded !=null)
 {
     // your update query
 }
 else
 {
   // your insert query
 }

You need to read something from database, than compare if it is null. If compared cell is null you need to insert data, otherwise update it.

take hiddenfield and when You edit data of gridview You set hiddenfield value to command argument of gridview so when You update, hiddenfield will have value and on page load in not ispostback clear value of hiddenfield and after submit also clear value of hiddenfield
Your condition would be on submit button click
if (hdSrNo.value)>0
{
//update
}
else
{
//insert
}
hope this will help You..
