Solution 2

While using DataAdapter following steps are followed:
1) Open a connection
2) Create a DataAdapter
3) Fill a table using DataAdapter
4) Bind table to GridView

Reference from below link:http://www.dotnetperls.com/sqldataadapter[^]

If above steps are followed, ensure the "AutoGenerateColumns" property of GridView is set to TRUE or you will need to define each column of the gridview. I think GridView should be visible using these steps. Please reply back if otherwise.

try this:-

private void binddata()
        {
            string connstring = @"Data Source=LENOVO-41B3F2CE\SQLEXPRESS;Initial Catalog=IMS;Integrated Security=True;Pooling=False";
            string query = "SELECT * FROM ['ISB VAS Nodes$']";
            SqlConnection con = new SqlConnection(connstring );
            SqlCommand cmd = new SqlCommand(selectSQL, con);
            SqlDataAdapter adapter = new SqlDataAdapter(cmd);
            DataTable dt = new DataTable();
            da.Fill(dt);

            GridView1.DataSource = dt;
            GridView1.DataBind();
}

Solution 1

Debug your code and check the number of rows in DataTable dt. It's because there is no rows in the DataTable your gridview is binding but not showing any records.

You are right Amit.U have to check whether the datatable fill with value or not then only it will display.
