I am having a problem with the sql update statement in c#. This click event tests between either "edit" or "new" mode and then uses the proper sql statement. The Insert statement works fine but the Update statement does not update. I created a break point and stepped thru and it does not throw any errors and looks like it executes but the database is not updated. I don't know if I am over thinking it and the obvious is right in front of me.
The code for the click event is below.
Thanks in advance for your help.
protected void btnCustomerUpdate_Click(object sender, EventArgs e)
{
string Mode = Request.QueryString["MODE"];
if (Mode == "E")
{
int CustomerID = int.Parse(Request.QueryString["ID"]);

SqlConnection Conn = new SqlConnection(ConfigurationManager.ConnectionStrings["MyData"].ConnectionString);

//Declare the Command
SqlCommand cmd = new SqlCommand(sql, Conn);
try
{
//Make the connection
Conn.Open();
