Where did you put that code? Which event?

SViki 21-Mar-14 6:36am

public void BindData()
{
con.Open();
cmd = new SqlCommand("select language_id, language_name ,language_desc from tbl_language where isactive=1 and ref_country_id = " + Convert.ToInt32(ddlCountry.SelectedValue.ToString()), con);
da = new SqlDataAdapter(cmd);
da.Fill(ds);

GridView1.DataSource = ds;
GridView1.DataBind();
GridView1.Visible = true;
// GridView1.Columns[0].Visible = false;

con.Close();
}

Because they are automatically generated you'll need to do it in a later event because they don't actually exist at that point, I believe. Is this winforms or asp.net?

For your purpose, you should be using DataKeyNames[^]
Briefly, set the DataKeyNames property of the gridview to the id field. During databinding, the GridView will look for a field named id and used it the primary key for each row in the GridView. This way, you do not have to display the id yet still being able to retrieve it.
