I am writing a code which updates the database using datagridview(windows forms).
I am able to load the data into the forms,but am not able to update the same.
I tried using the below code to update,but its not working.
Can anyone point the issue within the code or what changes should i do to make the code working?

C#

string con = "Data Source=01HW306775\\SQLEXPRESS;Integrated Security=TRUE;";
string query = "Select * from Customers";
sda = new SqlDataAdapter(query, con);
SqlCommandBuilder sc1 = new SqlCommandBuilder(sda);
DataSet ds1 = new DataSet();
DataTable db1 = new DataTable();
sda.Fill(ds1);
dataGridView1.DataSource = ds1.Tables[0];
sda.Update((ds1,table_name1);

C#

sda.Update((ds1,table_name1);

is this a immediate line after

C#

dataGridView1.DataSource = ds1.Tables[0];

...???

if yes, it doest make any difference. you are updating the same data back in the table. rather u should make

C#

sda

and

C#

ds1

and private members of class and in any of the events of your choice on gridview or you can call separate menthod which contains these lines based on some condition.

hope this helps..
