Hi ,
Try this

protected void GridView1_RowUpdating(object sender, GridViewUpdateEventArgs e)
    {
        if (((CheckBox)GridView1.Rows[e.RowIndex].FindControl("CheckBox1")) is CheckBox)
        {
            using (
                SqlConnection con =
                    new SqlConnection(ConfigurationManager.ConnectionStrings["testConnectionString"].ConnectionString))
            {
                con.Open();
                SqlCommand cmd = new SqlCommand("UPDATE dbo.cate  SET cate = @cate , chk = @chk  where id  = @id", con);
                cmd.Parameters.AddWithValue("@cate",
                                            ((TextBox)GridView1.Rows[e.RowIndex].FindControl("TextBox1")).Text);
 
                cmd.Parameters.AddWithValue("@chk",
                                            ((CheckBox)GridView1.Rows[e.RowIndex].FindControl("CheckBox1")).Checked);
 
                cmd.Parameters.AddWithValue("@id",
                                            ((Label)GridView1.Rows[e.RowIndex].FindControl("Label1")).Text);
 
                cmd.CommandType = System.Data.CommandType.Text;
                cmd.ExecuteNonQuery();
                cmd.Dispose();
 
                GridView1.EditIndex = -1;
                bind();
            }
        }
